无法访问串口），开发阶段使用**文件桥接模式**：\n\n```\n┌────────────────────────────────────┐\n│ APK (测试用) │\n│ simple_app/MainActivity.java │\n│ - 点击按钮 → 读文件 → 显示版本号 │\n│ 无需任何权限，不操作串口

|\n| `mcu-contract.aar` | **接口定义库**，与 SDK 配对 | `release/qsmw-contract.aar` (编译后) |\n| `McuClient.java` | API 参考（含在 AAR 内） | `sdk/src/main/java/.../McuClient.java` |\n| `IMcuService.aidl` | AIDL 接口定义（含在 AAR 内） | `contract/src/main/aidl/.../IMcuService.aidl` |\n| `qsjnic.md` | **本文档** | `test_Update/qsjnic.md` |\n\n### 编译方式\n\n在项目根目录执行：\n\n```bash\n./gradlew :sdk:assembleRelease :contract:assembleRelease\n```\n\n产物在：\n- `sdk/build/outputs/aar/sdk-release.aar` → 改名为 `mcu-sdk.aar`\n- `contract/build/outputs/aar/contract-release.aar` → 改名为 `mcu-contract.aar`\n\n一键打包交付物的方式：\n\n```bash\n./gradlew packRelease\n```\n\n产物在 `release/` 目录：\n- `qsmw-sdk.aar` — SDK\n- `qsmw-contract.aar` — 接口定义\n- `qsmw-service.apk` — 系统服务 APK（预置到系统）\n- `qsmw-demos.zip` — 三个示例项目（vehicle-demo, radio-demo, ota-demo）\n\n---\n\n## 四、APK 集成步骤\n\n### 步骤 1：添加 AAR 依赖\n\n在 APK 项目的 `build.gradle.kts` 中添加：\n\n```kotlin\ndependencies {\n implementation(files(\"libs/mcu-sdk.aar\"))\n implementation(files(\"libs/mcu-contract.aar\"))\n}\n```\n\n### 步骤 2：添加权限\n\n在 `AndroidManifest.xml` 中添加：\n\n```xml\n\n```\n\n### 步骤 3：在代码中调用\n\n**获取 MCU 版本号：**\n\n```java\nimport com.qsjnic.mcu.sdk.McuClient;\n\n// 初始化（Application.onCreate 中执行一次）\nMcuClient.getInstance().init(getApplicationContext());\n\n// 检查连接\nif (McuClient.getInstance().isReady() && McuClient.getInstance().isLinkAlive()) {\n // 获取版本号（从 Service 缓存读取，非阻塞）\n McuVersion version = McuClient.getInstance().vehicle().getMcuVersion();\n if (version != null) {\n String swVersion = version.getSwVersion(); // \"E112C069XZA0120015\"\n String swBuild = version.getSwBuild(); // \"0302_20260512\"\n }\n}\n```\n\n**监听 MCU 推送的数据：**\n\n```java\nimport com.qsjnic.mcu.sdk.VehicleListener;\n\nMcuClient.getInstance().vehicle().addListener(new VehicleListener() {\n @Override public void onMcuVersion(McuVersion v) {\n // MCU 版本号更新时回调\n runOnUiThread(() -> textView.setText(v.getSwVersion()));\n }\n @Override public void onCarSpeed(int speedKmh) {\n // 车速更新 (需要 CAN 环境)\n }\n @Override public void onVoltage(int mv) {\n // 电压更新 (需要 CAN 环境)\n }\n // ... 共 25 个回调\n});\n\n// Activity onDestroy 时移除监听\nMcuClient.getInstance().vehicle().removeListener(listener);\nMcuClient.getInstance().release();\n```\n\n**发送命令给 MCU：**\n\n```java\n// Public 域\nMcuClient.getInstance().vehicle().requestInitInfo(); // 0x81\nMcuClient.getInstance().vehicle().setMute(true); // 0x82\nMcuClient.getInstance().vehicle().setBacklight(50, 50); // 0x84\nMcuClient.getInstance().vehicle().setAmpPower(true); // 0x8A\n\n// Radio 域\nMcuClient.getInstance().radio().setBand(0); // 0x83 FM\nMcuClient.getInstance().radio().setFrequency(8750); // 0x84 87.5MHz\nMcuClient.getInstance().radio().setAntPower(true); // 0x86\n\n// Upgrade 域\nMcuClient.getInstance().upgrade().startUpgrade(path); // OTA\n```\n\n### 完整示例代码\n\n```java\npublic class MainActivity extends Activity {\n private TextView tvVersion;\n\n @Override\n protected void onCreate(Bundle savedInstanceState) {\n super.onCreate(savedInstanceState);\n setContentView(R.layout.activity_main);\n tvVersion = findViewById(R.id.tvVersion);\n\n // 初始化 SDK\n McuClient.getInstance().init(getApplicationContext());\n\n // 监听版本号\n McuClient.getInstance().vehicle().addListener(new VehicleListener() {\n @Override public void onMcuVersion(McuVersion v) {\n runOnUiThread(() -> {\n tvVersion.setText(v.getSwVersion());\n });\n }\n });\n\n // 主动请求版本号\n findViewById(R.id.btnGetVersion).setOnClickListener(v -> {\n McuVersion v = McuClient.getInstance().vehicle().getMcuVersion();\n if (v != null) tvVersion.setText(v.getSwVersion());\n });\n }\n}\n```\n\n---\n\n## 五、系统集成（给车机厂商）\n\n### Service APK 预置\n\n`qsmw-service.apk` 需要预置到车机系统的 `/system/priv-app/McuService/` 目录：\n\n```xml\n\nPRODUCT_PACKAGES += QsmwService\n\n\nprebuilt_apk {\n name: \"QsmwService\",\n src: \"qsmw-service.apk\",\n privileged: true,\n persistent: true,\n required: [\"libmcu_jni\", \"libmcu_api\"],\n}\n```\n\n### SELinux 策略\n\n需要添加以下 SELinux 规则：\n\n```\n# 允许 Service 访问串口设备\nallow priv_app serial_device:chr_file { open read write ioctl };\n\n# 允许 APK 绑定 Service\nallow untrusted_app mcud_service:service_manager find;\nallow untrusted_app mcud_service:fd use;\n```\n\n### init.rc 开机自启\n\n```rc\n# 确保串口权限\non boot\n chmod 0660 /dev/ttyS7\n chown system system /dev/ttyS7\n\n# Service 自启动 (已经 persistent=true, 不需要额外配置)\n```\n\n---\n\n## 六、开发阶段快速参考\n\n### 测试命令速查\n\n```bash\n# === 前置条件 (每次车机重启后执行一次) ===\nadb root\nadb shell chmod 666 /dev/ttyS7\n\n# === C 程序测试 (推荐) ===\nadb shell /data/local/tmp/mcu_interface_test # 测试全部 28 个接口\n\n# === 获取版本号 (APK 需要) ===\nadb shell /data/local/tmp/mcu_daemon # 执行一次\nadb shell cat /data/local/tmp/mcu_version.txt # 查看结果\n\n# === 后台守护进程 (APK 随时可读) ===\nadb shell /data/local/tmp/mcu_daemon & # 后台执行\n\n# === APK 安装 ===\n./gradlew :simple_app:assembleDebug\nadb install -r test_Update/simple_app/build/outputs/apk/debug/simple_app-debug.apk\nadb shell am start -n com.qsjnic.mcu.simple/.MainActivity\n\n# === MCU 升级测试 ===\nadb shell /data/local/tmp/mcu_structured_test_mod --live-upgrade \\\n --upgrade-bin /data/local/tmp/mcu_app.bin\n\n# === 查看日志 ===\nadb logcat -s QsMcuSystemService:McuJni:McuLink\n```\n\n### 关键路径\n\n```\ntest_Update/\n├── mcu_api.c / .h # C

`mcu_api.c`, `mcu_interface_test.c` |\n\n---\n\n## 多 APK 通信流程\n\n```\nStep 1: APK 调用 McuClient.getInstance().init(context)\n → bindService(Intent(\"cn.qsjnic.IMcuService\"))\n → Service 的 onBind() 返回 McuBinder (IMcuService.Stub)\n → APK 拿到 IMcuService 代理\n\nStep 2: APK 调用 vehicle().setMute(true)\n → McuVehicleClient 调 IMcuService.setMute(true)\n → Binder 跨进程 → McuBinder.setMute()\n → McuLink.sendAndWaitAck(0x01, 0x82, {0x01}, 1500)\n\nStep 3: JNI nativeMcuLinkSendAndWaitAck()\n → C 层构建帧 FF AA 00 0A seq 06 01 82 01 CS\n → write(\"/dev/ttyS7\", frame, 10)\n → select() 等 ACK\n\nStep 4: MCU 收到帧, 解析 seq, 处理命令, 回复 ACK\n → C 层读到 ACK, 返回 seq\n → JNI 返回 → McuBinder 返回 OK\n → Binder 返回 → APK 的 setMute() 返回 0\n\nStep 5（并行）: MCU 主动推送 M2A 帧\n → C 层的读线程收到 DATA 帧\n → 自动回 ACK + 推入 M2A 事件队列\n → JNI 回调 → FrameRouter → DomainBus\n → VehicleFeature / RadioFeature 更新缓存\n → broadcastRawFrame → RemoteCallbackList → APK 监听器\n```\n\n---\n\n## Service 为什么不需要 root\n\n**生产环境：** Service APK 用 `android:protectionLevel=\"signature|privileged\"` 签名。\n- 作为系统应用安装在 `/system/priv-app/`\n- 运行在 `priv_app` SELinux 域\n- 直接有权限 `open(\"/dev/ttyS7\")`\n- 不需要 root\n\n**开发测试：** 用 adb root 直接运行 C 测试程序\n```bash\nadb root\nadb shell chmod 666 /dev/ttyS7\nadb shell /data/local/tmp/mcu_test mcu_req_init_info\n```\n\n---\n\n## 已修复的 Bug\n\n| # | 问题 | 修复 |\n|---|------|------|\n| Bug #1 | 循环探测连发两帧不等待 ACK | 改用 `sendAndWaitAck`，等第一个 ACK 再发第二个 |\n| Bug #2 | 所有 typed AIDL 方法用 fire-and-forget | 改为 `sendAndWaitAck(..., 1500)` |\n| Bug #4 | `sendAndWaitAck` 已实现但无人用 | 同上（Bug #2 已覆盖） |\n| Bug #3 | C 层等 ACK 期间丢弃 M2A 帧 | 加 M2A 事件队列，帧入队列不丢失 |\n\n---\n\n## 半双工串口与消息队列\n\n串口是半双工，同时只能有一个请求在飞。当前方案：\n\n```\nAPK A: sendCommand →┐ ┌─→ 执行 REQ_MUTE → 等 ACK → 回调 A\n ├─→ 消息队列(FIFO) ──┼─→ 执行 SET_FREQ → 等 ACK → 回调 B\nAPK B: sendCommand →┘ └─→ 执行 GET_VER → 等 ACK → 回调 C\n```\n\n- `sendAndWaitAck` 保证发帧后等 ACK 才返回\n- 未来加 `LinkedBlockingQueue` 做消息队列，彻底串行化\n- MCU 推送的 M2A 帧通过事件队列独立上报，不受影响" } ] }, { "role": "assistant",

|\n| Demo 安装后打开空白，无数据显示 | vehicle-demo 所有 TextView 显示 \"?\" |\n| adb shell 查看 Service 状态 | `Link alive: false`, `Link open: false`, `TX count: 0` |\n| logcat 无 MCU 数据回调 | 看不到 `onVoltage` / `onMcuVersion` / `onFreqChanged` 等日志 |\n| 直接 `adb install` 后运行 | Service 进程存在，但串口未打开 |\n\n**根因**: `qsmw-service.apk` 需要访问 `/dev/ttyS7` 串口设备。该设备权限为 `root:system crw-rw----`，普通应用（uid 101xxx）没有读写权限。\n\n**解决方案**: 将 APK 作为 **Privileged App** 预置到 `/system/priv-app/`，使 Service 以 `system` UID 运行，获得串口访问权限。\n\n---\n\n## 二、方案 A（推荐）：系统镜像预置\n\n### 2.1 文件清单\n\n将以下文件从乙方交付包复制到您的系统源码目录：\n\n```\nvendor///qsmw/\n├── qsmw-service.apk ← 乙方交付\n├── privapp-permissions-com.qsjnic.mcu.xml ← 新建，见 2.3\n└── Android.mk 或 Android.bp ← 新建，见 2.2\n```\n\n### 2.2 Build

核心）\n\n### 4.1 前置条件\n\n| 检查项 | 命令 | 预期结果 |\n| -------------- | ---------------------------------------- | ----------------------------- |\n| Service 已运行 | `adb shell ps -A \\| grep qsjnic` | 看到 `com.qsjnic.mcu.service` |\n| 串口已打开 | `adb shell dumpsys activity service ...` | `Link open: true` |\n| 链路已建立 | 同上 | `Link alive: true` |\n| MCU 有响应 | `adb shell logcat -s McuLink:D` | 看到心跳收发日志 |\n\n### 4.2 安装 Radio Demo\n\n```bash\nadb install -r radio-demo.apk\nadb shell am start -n com.qsjnic.demo.radio/.MainActivity\n```\n\n### 4.3 功能验证清单\n\n在 radio-demo 界面依次点击并观察：\n\n| 步骤 | 操作 | 预期现象 | 验证点 |\n| ---- | ----------------------- | ------------------------------------- | ------------------------- |\n| 1 | 点击 **\"Init Range\"** | 无报错 | `setFreqRange` 命令下发 |\n| 2 | 点击 **\"Set Band: FM\"** | `tvBand` 变为 \"Band: FM\" | `setBand(0)` 生效 |\n| 3 | 点击 **\"Tune 87.5MHz\"** | `tvFreq` 变为 \"Freq: 8750 (\\*100KHz)\" | `setFrequency(8750)` 生效 |\n| 4 | 点击 **\"Ant Power ON\"** | 无报错 | `setAntPower(true)` 生效 |\n| 5 | 点击 **\"Seek Forward\"** | 频率数值变化 | `seekForward()` 生效 |\n| 6 | 点击 **\"Seek Stop\"** | 频率停止变化 | `seekStop()` 生效 |\n| 7 | 观察自动冒烟测试 | 3s 后自动执行频段初始化 + FM 设置 | Demo 内置自动验证序列 |\n\n### 4.4 logcat 抓包验证（推荐）\n\n```bash\n# 清空日志\nadb logcat -c\n\n# 启动 radio-demo\nadb shell am start -n com.qsjnic.demo.radio/.MainActivity\n\n# 抓取 30 秒日志\nadb logcat -v time | grep -E \"RadioDemo|RadioManager|McuRadioClient|McuLink|onFreqChanged|onPsPty|setBand|setFrequency|setFreqRange|seek\" > radio_test.log\n```\n\n**关键日志特征**（验证通过）：\n\n```\nI RadioDemo: listener.onFreqChanged RadioState{band=0 freq=8750 signal=0}\nI RadioDemo: listener.onPsPty pi=1234 pty=1 ps=RDS\nD McuLink: TX band=0x05 cmd=0x83 payload=00 [SET_BAND FM]\nD McuLink: RX band=0x05 cmd=0x01 payload=... [RADIO_FREQ FM 8750MHz]\n```\n\n### 4.5 常见问题排查\n\n#### Q1: radio-demo 启动后所有数据为 \"?\"\n\n**排查**：\n\n```bash\nadb shell dumpsys activity service com.qsjnic.mcu.service/.QsMcuSystemService\n```\n\n- 若 `Link alive: false` → 见第二节，检查 Service 是否以 system UID 运行\n- 若 `Link alive: true` → MCU 未上报 Radio 数据，检查 MCU 固件是否支持 Radio 域\n\n#### Q2: 点击 Set Band / Tune 无反应\n\n**排查**：\n\n```bash\nadb shell logcat -s McuRadioClient:D\n```\n\n- 若看到 `setBand returned -4` → Service 未绑定（检查 Binder 链路）\n- 若看到 `setBand returned 0` 但 MCU 无响应 → 检查 MCU 侧 Radio 功能是否启用\n\n#### Q3: Seek 后频率不变化\n\n**排查**：\n\n- 确认天线电源已打开（点击 \"Ant Power ON\"）\n- 确认当前区域有 FM 信号覆盖\n- 检查 logcat 是否有 `onFreqChanged` 回调\n\n#### Q4: Radio 回调触发但 UI 不更新\n\n**排查**：\n\n- 确认 radio-demo 的 `RadioListener` 已注册\n- 检查 `adb shell logcat | grep RadioDemo` 是否有回调日志\n- UI 更新在主线程，若 ANR 请检查是否有阻塞操作\n\n---\n\n## 五、快速检查清单\n\n集成完成后，请甲方逐项确认：\n\n- [ ] `qsmw-service.apk` 已预置到 `/system/priv-app/QsmwService/`\n- [ ] APK 已用甲方 platform 密钥签名（或 build 系统重签）\n- [ ] `privapp-permissions-com.qsjnic.mcu.xml` 已放到 `/system/etc/permissions/`\n- [ ] `/dev/ttyS7` 权限为 `0660 system:system`\n- [ ] 重启后 `ps -A | grep qsjnic` 能看到服务进程\n- [ ] `dumpsys` 显示 `Link alive: true`\n- [ ] vehicle-demo 安装后 5 秒内显示电压、ACC/IG 状态\n- [ ] radio-demo 点击 \"Set Band FM\" + \"Tune 87.5MHz\" 后频率正确显示\n- [ ] radio-demo 点击 \"Seek Forward\" 后频率发生变化\n\n---\n\n---\n\n## 六、联系支持\n\n| 问题类型 | 联系方式 |\n| ----------------------------- | -------------------- |\n| Service / SDK 代码缺陷 | 车机项目中间件研发组 |\n| 镜像签名 / SELinux / 预置流程 | 甲方系统镜像团队 |\n| MCU 固件 Radio 功能不响应 | 甲方 MCU 厂商 |\n| 本 SOP 操作疑问 | 车机项目中间件研发组 |" } ] }, { "role": "assistant", "content": [ { "type": "thinking", "thinking": "Now let me also look at the SDK's radio client and the radio demo to understand what commands are being sent and what audio pipeline setup might be missing.

Let me also check the QsMcuSystemService to see how RadioFeature is wired in, and look for any ADC/audio-related code.\n\nThe key issue is: The radio control commands (setBand, setFrequency, seek, antPower etc.) work through the serial protocol to the MCU. The MCU forwards these to the radio chip. The radio chip tunes to stations and sends back RDS/frequency/signal data via the same serial path. However, the **audio** from the radio chip needs to be routed through an ADC on the SoC (ADC0 channel) to reach the Android audio system, and that ADC channel is not being enabled.\n\nThe engineer's comment \"按照硬件图adc0通道需要在应用层打开通道\" - \"According to the hardware schematic, the ADC0 channel needs to be opened at the application layer.\"\n\nThis means the radio chip's analog audio output goes to the SoC's ADC0 input. That ADC needs to be configured/enabled from Android userspace - probably through:\n1. A GPIO control to enable the radio chip's analog audio output\n2. An audio route/patch in the ALSA or audio HAL\n3. A sysfs node or vendor HAL interface\n\nLet me check the QsMcuSystemService to see if there's any audio-related functionality." }, { "type": "tool_use", "id": "call_00_Ib936mlQt5T2OdDkANEA0385", "name": "exec_shell", "input": { "command": "cat /Users/admin/workspace/jyq/car/qsjnic/service/src/main/java/com/qsjnic/mcu/service/QsMcuSystemService.java" } }, { "type": "tool_use", "id": "call_01_b0P67o4g4X5vQLouOmR22641", "name": "exec_shell", "input": { "command": "cat /Users/admin/workspace/jyq/car/qsjnic/service/src/main/java/com/qsjnic/mcu/service/McuBinder.java" } } ] }, { "role": "user", "content": [ { "type": "tool_result", "tool_use_id": "call_00_Ib936mlQt5T2OdDkANEA0385", "content": "package com.qsjnic.mcu.service;\n\nimport android.app.Notification;\nimport android.app.NotificationChannel;\nimport android.app.NotificationManager;\nimport android.app.Service;\nimport android.content.Intent;\nimport android.os.Build;\nimport android.os.Handler;\nimport android.os.IBinder;\nimport android.os.Looper;\nimport android.os.Process;\nimport android.os.RemoteCallbackList;\nimport android.util.Log;\n\nimport androidx.annotation.Nullable;\n\nimport java.io.FileDescriptor;\nimport java.io.PrintWriter;\n\nimport com.qsjnic.mcu.contract.IMcuService;\nimport com.qsjnic.mcu.contract.IMcuFrameListener;\n\nimport com.qsjnic.mcu.service.feature.DomainBus;\nimport com.qsjnic.mcu.service.feature.VehicleFeature;\nimport com.qsjnic.mcu.service.feature.RadioFeature;\nimport com.qsjnic.mcu.service.feature.UpgradeFeature;\n\n/**\n * Stage A2 skeleton: empty long-running service that only proves the process\n * is started and stays alive.

Let me interpret what I can see:\n\nKey signals from the schematic:\n- `Al_ADC0_L` and `Al_ADC0_R` - Audio ADC0 left and right channels\n- `Al_ADC1_R` - Audio ADC1 right channel\n- `Al_ADC2_L`, `Al_ADC2_R` - Audio ADC2 left and right\n- `AMIC_LP`, `AMIC_LN` - Analog microphone positive/negative (left)\n- `AMIC_RP`, `AMIC_RN` - Analog microphone positive/negative (right)\n- `AMIC_BIAS` - Microphone bias voltage\n- `DAB_R` - Digital Audio Broadcasting right channel\n- Various capacitors (225/6.3V, 47UF/25V)\n- `Al_VREF` - ADC voltage reference\n\nSo the schematic shows that the audio ADC channels (ADC0_L, ADC0_R) are connected to the SoC. These are the ADC channels that need to be enabled/configured to get audio from the radio chip.\n\nThe engineer said \"ADC0通道需要在应用层打开\" - the ADC0 channel needs to be opened at the application layer. This means:\n1. The hardware connection exists - radio chip analog audio out → SoC ADC0 in\n2. But the SoC's ADC0 is not enabled/configured from the Android side\n3. This is typically done through either:\n a. GPIO control on the SoC\n b. Audio HAL configuration (tinyalsa/tinymix)\n c. A vendor-specific HAL interface\n d. Sysfs node access\n\nLet me now look at what the kimi analysis said more carefully. The user pasted it before the image:\n\n```\n▌ MCU 控制面通了，但 Android 层的 \"音频数据面\" 没有建立起来。\n\n工程师说的\"Android 层负责打开 adc0 通道\"，不是指调 tinymix，而是指通过某个 Vendor HAL 层接口（很可能就是那个缺失的 mcu_hal 服务）来完成：\n\n1. 向收音机芯片发送额外的初始化/音频使能序列（可能通过 I2C/SPI，不是串口）\n2. 在 Android Audio HAL 中建立 FM Tuner → bus0_media_out 的音频 patch\n3. 或者通过 GPIO 使能收音机芯片的模拟音频输出\n\n你现在有几个选择：\n选项 A（最快）：把工程师给的参考指令发给我，我直接执行。不要再让我盲调 tinymix 了。\n选项 B：检查系统中是否漏装了 mcu_hal 相关的 vendor 服务或 APK。正常的收音机系统应该有这个 HAL。\n选项 C：如果 mcu_hal 确实不存在，我们需要找到替代方法 —— 比如通过 broadcastradio HAL 的隐藏接口、或者某个 sysfs/gpio 节点来手动\"打开通道\"。\n\n你选哪个？或者直接把工程师的指令给我。\n```\n\nSo the user attached the image (hardware schematic) and is asking me to analyze it and help decide which option to pursue. Based on what OCR revealed:\n\nThe schematic shows the audio ADC connections (ADC0_L, ADC0_R, etc.) - these are the SoC's internal audio ADCs. The radio chip's analog audio output routes through these ADCs into the Android audio system.\n\nNow, the question is: who enables these ADC channels? In Android, this is typically handled by:\n1. The **Audio HAL** (audio.primary.xxxx.so) - which configures the audio routes using ALSA/tinyalsa\n2. A **vendor-specific HAL** (like mcu_hal) that knows how to configure the SoC's audio mixing/routing\n3. Direct **sysfs/gpio** access to turn on the ADC\n\nGiven that:\n- The system already has a working MCU serial protocol stack\n- The radio demo can tune and scan stations\n- But there's no audio\n- The engineer explicitly said \"ADC0通道需要在应用层打开\"\n- The schematic shows ADC0 L/R are present in the SoC\n\nThe most practical path forward depends on what hardware/SoC this is and what vendor HALs are available.\n\nLet me look for any hints about the SoC platform or vendor HALs in the project." }, { "type": "text", "text": "Good — the OCR extracted the schematic labels.

Java SDK 接口定义（示例）需提供以下核心 API（可根据实际增减）：java// 初始化，传入串口路径（默认 /dev/ttyS7）public class CarSerialSDK { public static native boolean init(String ttyPath); public static native void deinit(); // 车辆信号回调注册 public static native void setVehicleCallback(VehicleCallback callback); // 收音机回调注册 public static native void setRadioCallback(RadioCallback callback); // 升级回调注册 public static native void setUpdateCallback(UpdateCallback callback); // 主动发送命令（同步/异步均可） public static native int setRadioFreq(int band, int freq); // 0=FM,1=AM public static native int setRadioSeek(int seekMode, int ptyType); public static native int setRadioSwitch(int switchType, boolean on); public static native int setBacklight(int percent); public static native int setAmpPower(boolean on); public static native int sendMcuUpgradeData(byte[] data, int offset, int len); // ... 其他接口}// 回调示例interface VehicleCallback { void onAccStateChanged(boolean on); void onReverseStateChanged(boolean on); void onCarSpeed(int speedKmh); void onBatteryVoltage(int mv); void onMcuVersion(String version);}interface RadioCallback { void onFreqChanged(int band, int freq, boolean stereo, boolean valid); void onRdsPs(String ps); void onRdsRt(String rt); void onSignalStrength(int strength);}5. 交付物清单NO交付物说明2预编译 .so 库提供 arm64-v8a 架构的动态库，及对应的 Android 库（.aar 或 .so + 接口 jar）。3Java SDK 源码封装 JNI 调用和回调接口，提供易于使用的 API。4Demo App 源码一个简单的 Android 应用，演示如何初始化 SDK、注册回调、调频、显示车速等，供我方集成参考。5技术文档- SDK 集成指南（添加依赖、权限配置、初始化流程）- API 参考手册（每个接口参数、返回值、错误码）- 协议实现对照表（说明各命令对应协议文档中的哪一条）- 调试说明（如何开启 hex 日志、常见问题排查）6测试报告功能测试（覆盖所有协议命令）、压力测试（长时间运行、频繁读写）、异常测试（断线重连、超时重试）。6. 调试日志规范6.1 日志级别与输出内容级别触发场景输出内容示例ERROR系统调用失败（open/read/write/ioctl 返回 -1）；协议校验失败；重试超过上限；设备断连open /dev/ttyS7 failed: Permission denied (errno=13)Checksum error: calc=0x2A, recv=0x3BWARN重试（如 ACK 超时重发）；心跳丢失；非致命协议异常Heartbeat timeout, retry 1/3Unexpected frame type 0x09, ignoredINFO设备打开/关闭；建链成功/失败；心跳启停；升级开始/结束；重要的状态变化Device opened, fd=7Link established after 2 retriesEntering MCU upgrade modeDEBUG所有发送和接收的原始数据（Hex 格式）；帧解析后的关键字段；进入/退出关键函数TX len=12, hex: FF AA 00 0C 01 06 05 83 00 26 9F 5ARX frame: type=0x06, msgType=0x01, cmd=0x01, len=96.2 实现重点6.2.1 设备操作日志每次 open 设备：记录路径、返回的 fd、errno（如果失败）。每次 close 设备：记录 fd。每次 read/write 调用：记录操作类型、请求长度、实际返回长度、errno。6.2.2 原始数据收发日志（Hex 格式）在 write 之前，将待发送的数据字节以十六进制字符串形式输出，一行完整帧。在 read 之后，将从串口读到的原始字节以十六进制字符串形式输出（建议每帧单独一行，如长度较大可截断但需保留首尾）。格式要求：TX len=XX, hex: XX XX XX ...；RX len=YY, hex: YY YY YY ...。6.2.3 协议帧解析日志每解析出一个完整帧（包括帧头、长度、序列号、帧类型、MsgType、Cmd、数据、校验和），至少输出：帧类型（FrameType）、MsgType、Cmd、序列号、数据长度、校验和是否通过。对于心跳帧、ACK 帧，单独输出标识。6.2.4 链路状态日志建链发起、超时、重试、成功、失败。心跳发送与接收：每次发送心跳及收到对应 ACK 时输出。链路断开检测及重连尝试。6.2.5 业务命令日志发送任何主动命令（如设置频率、搜索、设置背光）时，输出命令名称及参数。收到异步上报（如车速、倒车、收音机频率）时，输出解析后的业务数据。6.2.6 错误与异常日志任何系统调用失败，必须输出 strerror(errno) 和 errno 值。校验和错误、帧长度异常、无效 MsgType/Cmd 等协议异常。ACK 超时、重试次数达到上限。6.3 日志开关与动态控制必须实现编译期日志级别宏（如 LOG_LEVEL_DEBUG、LOG_LEVEL_INFO），方便我方在开发阶段开启 DEBUG，量产阶段关闭。建议实现运行时控制：通过 Android 系统属性（如 persist.carserial.log.level）动态调整日志级别，无需重新编译。示例：cint log_level = __system_property_get("persist.carserial.log.level", value);if (strcmp(value, "DEBUG") == 0) enable_debug = 1;默认出厂配置为 INFO 级别，DEBUG 级别仅在开发/联调阶段开启。6.4 日志性能与安全要求DEBUG 级别的 Hex 日志不得影响串口读写实时性（建议使用异步日志缓存或仅在可控频率下输出）。生产版本（Release 编译）应移除或条件编译掉 DEBUG 级别日志，避免日志刷屏和泄露敏感数据。日志中不得包含用户隐私信息（如 GPS 坐标、设备唯一标识等），仅保留技术调试数据。6.5 验收时需提供的日志示例提供一份完整的 logcat 输出文件，覆盖以下场景：设备上电 → 建链 → 心跳 → 发送收音机调频命令 → 收到频率上报 → 进入休眠 → 唤醒重连。模拟一次 MCU 升级过程（从请求升级到传输数据到结束）。模拟一次串口断线（例如拔线）后自动重连的过程。日志中必须清晰体现上述强制日志点的输出。7. 验收标准功能完整性：所有协议中我方指定的命令（见第 3 节）均可正常收发，MCU 正确响应。稳定性：连续运行 48 小时，无内存泄露、崩溃、串口死锁。心跳保持，无异常断链。并发安全：同时调用收音机和车辆接口（例如搜索电台的同时上报车速），数据不混乱，回调正常。升级测试：能够成功完成 MCU 固件升级（至少模拟升级流程）。日志：提供可开关的 hex 日志，方便与方案公司联调。文档：文档清晰，我方工程师可独立完成集成。\n/Users/admin/workspace/jyq/car/qsjnic/service/src/main/java/com/qsjnic/mcu/service/feature/RadioFeature.java: try { frameListeners.getBroadcastItem(i).onRadioStateChanged(snap); }" } ] }, { "role": "assistant", "content": [ { "type": "thinking", "thinking": "Excellent!

Java SDK 接口定义（示例）需提供以下核心 API（可根据实际增减）：java// 初始化，传入串口路径（默认 /dev/ttyS7）public class CarSerialSDK { public static native boolean init(String ttyPath); public static native void deinit(); // 车辆信号回调注册 public static native void setVehicleCallback(VehicleCallback callback); // 收音机回调注册 public static native void setRadioCallback(RadioCallback callback); // 升级回调注册 public static native void setUpdateCallback(UpdateCallback callback); // 主动发送命令（同步/异步均可） public static native int setRadioFreq(int band, int freq); // 0=FM,1=AM public static native int setRadioSeek(int seekMode, int ptyType); public static native int setRadioSwitch(int switchType, boolean on); public static native int setBacklight(int percent); public static native int setAmpPower(boolean on); public static native int sendMcuUpgradeData(byte[] data, int offset, int len); // ... 其他接口}// 回调示例interface VehicleCallback { void onAccStateChanged(boolean on); void onReverseStateChanged(boolean on); void onCarSpeed(int speedKmh); void onBatteryVoltage(int mv); void onMcuVersion(String version);}interface RadioCallback { void onFreqChanged(int band, int freq, boolean stereo, boolean valid); void onRdsPs(String ps); void onRdsRt(String rt); void onSignalStrength(int strength);}5. 交付物清单NO交付物说明2预编译 .so 库提供 arm64-v8a 架构的动态库，及对应的 Android 库（.aar 或 .so + 接口 jar）。3Java SDK 源码封装 JNI 调用和回调接口，提供易于使用的 API。4Demo App 源码一个简单的 Android 应用，演示如何初始化 SDK、注册回调、调频、显示车速等，供我方集成参考。5技术文档- SDK 集成指南（添加依赖、权限配置、初始化流程）- API 参考手册（每个接口参数、返回值、错误码）- 协议实现对照表（说明各命令对应协议文档中的哪一条）- 调试说明（如何开启 hex 日志、常见问题排查）6测试报告功能测试（覆盖所有协议命令）、压力测试（长时间运行、频繁读写）、异常测试（断线重连、超时重试）。6. 调试日志规范6.1 日志级别与输出内容级别触发场景输出内容示例ERROR系统调用失败（open/read/write/ioctl 返回 -1）；协议校验失败；重试超过上限；设备断连open /dev/ttyS7 failed: Permission denied (errno=13)Checksum error: calc=0x2A, recv=0x3BWARN重试（如 ACK 超时重发）；心跳丢失；非致命协议异常Heartbeat timeout, retry 1/3Unexpected frame type 0x09, ignoredINFO设备打开/关闭；建链成功/失败；心跳启停；升级开始/结束；重要的状态变化Device opened, fd=7Link established after 2 retriesEntering MCU upgrade modeDEBUG所有发送和接收的原始数据（Hex 格式）；帧解析后的关键字段；进入/退出关键函数TX len=12, hex: FF AA 00 0C 01 06 05 83 00 26 9F 5ARX frame: type=0x06, msgType=0x01, cmd=0x01, len=96.2 实现重点6.2.1 设备操作日志每次 open 设备：记录路径、返回的 fd、errno（如果失败）。每次 close 设备：记录 fd。每次 read/write 调用：记录操作类型、请求长度、实际返回长度、errno。6.2.2 原始数据收发日志（Hex 格式）在 write 之前，将待发送的数据字节以十六进制字符串形式输出，一行完整帧。在 read 之后，将从串口读到的原始字节以十六进制字符串形式输出（建议每帧单独一行，如长度较大可截断但需保留首尾）。格式要求：TX len=XX, hex: XX XX XX ...；RX len=YY, hex: YY YY YY ...。6.2.3 协议帧解析日志每解析出一个完整帧（包括帧头、长度、序列号、帧类型、MsgType、Cmd、数据、校验和），至少输出：帧类型（FrameType）、MsgType、Cmd、序列号、数据长度、校验和是否通过。对于心跳帧、ACK 帧，单独输出标识。6.2.4 链路状态日志建链发起、超时、重试、成功、失败。心跳发送与接收：每次发送心跳及收到对应 ACK 时输出。链路断开检测及重连尝试。6.2.5 业务命令日志发送任何主动命令（如设置频率、搜索、设置背光）时，输出命令名称及参数。收到异步上报（如车速、倒车、收音机频率）时，输出解析后的业务数据。6.2.6 错误与异常日志任何系统调用失败，必须输出 strerror(errno) 和 errno 值。校验和错误、帧长度异常、无效 MsgType/Cmd 等协议异常。ACK 超时、重试次数达到上限。6.3 日志开关与动态控制必须实现编译期日志级别宏（如 LOG_LEVEL_DEBUG、LOG_LEVEL_INFO），方便我方在开发阶段开启 DEBUG，量产阶段关闭。建议实现运行时控制：通过 Android 系统属性（如 persist.carserial.log.level）动态调整日志级别，无需重新编译。示例：cint log_level = __system_property_get("persist.carserial.log.level", value);if (strcmp(value, "DEBUG") == 0) enable_debug = 1;默认出厂配置为 INFO 级别，DEBUG 级别仅在开发/联调阶段开启。6.4 日志性能与安全要求DEBUG 级别的 Hex 日志不得影响串口读写实时性（建议使用异步日志缓存或仅在可控频率下输出）。生产版本（Release 编译）应移除或条件编译掉 DEBUG 级别日志，避免日志刷屏和泄露敏感数据。日志中不得包含用户隐私信息（如 GPS 坐标、设备唯一标识等），仅保留技术调试数据。6.5 验收时需提供的日志示例提供一份完整的 logcat 输出文件，覆盖以下场景：设备上电 → 建链 → 心跳 → 发送收音机调频命令 → 收到频率上报 → 进入休眠 → 唤醒重连。模拟一次 MCU 升级过程（从请求升级到传输数据到结束）。模拟一次串口断线（例如拔线）后自动重连的过程。日志中必须清晰体现上述强制日志点的输出。7. 验收标准功能完整性：所有协议中我方指定的命令（见第 3 节）均可正常收发，MCU 正确响应。稳定性：连续运行 48 小时，无内存泄露、崩溃、串口死锁。心跳保持，无异常断链。并发安全：同时调用收音机和车辆接口（例如搜索电台的同时上报车速），数据不混乱，回调正常。升级测试：能够成功完成 MCU 固件升级（至少模拟升级流程）。日志：提供可开关的 hex 日志，方便与方案公司联调。文档：文档清晰，我方工程师可独立完成集成。\n/Users/admin/workspace/jyq/car/qsjnic/docs/phase_a_validation_20260516_beta3.md:> **设备**: 192.168.0.66:5555 (AUTO_on_RTD1861, Android 14)

Let me analyze:\n\nCritical controls for the radio audio path:\n\n1. **Audio Analog In1 Path** (ctl 30) = 0 ← This selects which analog input is routed to ADC1\n2. **Audio Analog In2 Path** (ctl 31) = 1 ← This selects which analog input is routed to ADC2\n3. **Master Capture Switch** (ctl 23) = Off/Off ← **CAPTURE IS DISABLED!** This needs to be ON\n4. **Analog In1 ADC Analog Gain** (ctl 37) = 1/1 ← Very low gain\n5. **Analog In2 ADC Analog Gain** (ctl 38) = 0/0 ← Zero gain!\n6. **Analog In1 ADC Digital Gain** (ctl 39) = 1/67/67 ← Low digital gain\n7. **Analog In2 ADC Digital Gain** (ctl 40) = 0/67/67 ← No digital gain for first channel\n8. **Analog In1 Differential Enable** (ctl 46) = 0/0 ← Single-ended mode (differential is off)\n9. **Analog In2 Differential Enable** (ctl 47) = 0/0\n10. **Mic Mute Enable** (ctl 48) = 3/0 ← \"3\" means mute is ON for some channels\n11. **AO Interface Power** (ctl 54) = 0 ← Interface power is OFF\n12. **Master Volume** (ctl 22) = 31/31 ← Max (good)\n\nThe radio chip's analog audio likely connects to one of the \"Analog In\" paths. Looking at the schematic:\n- Al_ADC0_L, Al_ADC0_R — these map to Analog In1 (since ADC0 corresponds to first analog input)\n- The value \"0\" for Audio Analog In1 Path means path 0 (which might be \"no input\" or a specific input selector)\n- The value \"1\" for Audio Analog In2 Path means path 1\n\nThe key things to try:\n1. Turn ON `Master Capture Switch` (ctl 23) — this enables the capture path\n2. Set `Analog In1 Path` to the correct value for the radio input\n3. Set `Mic Mute Enable` to 0 (unmute)\n4. Check what values are valid for the Audio Analog In Path controls\n\nBut I need to understand what values correspond to what physical inputs. Let me try the most common \"enabling\" sequence for this type of RTD SoC.\n\nLet me also look at the pcm device list. The radio chip likely outputs to a specific PCM device, and that PCM needs to be routed through the mixer.\n\nActually, let me think about this differently. The radio chip communicates with MCU over some interface (probably I2C connected to MCU, not directly to the SoC). The MCU tunes the radio chip, and the radio chip's analog audio output goes to the SoC's ADC0 inputs. \n\nThe question is: which ALSA mixer controls configure the ADC0 path?\n\nOn RTD1861, the typical audio routing is:\n- ADC0 → Analog In1\n- ADC1 → Analog In2\n- ADC2 → maybe different path\n\nThe \"Audio Analog In1 Path\" and \"Audio Analog In2 Path\" are mux selectors. The value probably maps to:\n- 0 = something (maybe disabled or specific input)\n- 1 = something else\n- etc.\n\nLet me try a sequence of operations to enable the capture path and see if we can get audio.\n\nActually, first let me try to check if there are any PCM devices that could be used for capture, and also check the alsa-ucm or audio policy configuration." }, { "type": "text", "text": "找到了关键的 mixer controls。现在让我探测音频通路的具体配置。" }, { "type": "tool_use", "id": "call_00_ZnLlWQq69p4MKToGoHVj7519", "name": "exec_shell", "input": { "command": "adb shell \"cat /proc/asound/pcm; echo '---'; ls /proc/asound/ 2>&1\" 2>&1" } }, { "type": "tool_use", "id": "call_01_Q6r5J0YsmfdDKHkidHvD5509", "name": "exec_shell", "input": { "command": "adb shell cat /proc/asound/card0/pcm*/info 2>&1 | head -60" } }, { "type": "tool_use", "id": "call_02_xHm2gaThzN2XwfnxkgNo6697", "name": "exec_shell", "input": { "command": "adb shell find /vendor -name \"*audio*\" -o -name \"*alsa*\" -o -name \"*rtd*\" 2>/dev/null | head -20" } } ] }, { "role": "user", "content": [ { "type": "tool_result", "tool_use_id": "call_00_ZnLlWQq69p4MKToGoHVj7519", "content": "00-00: Skip decoder normal/HDMI-RX : Skip decoder normal/HDMI-RX : playback 2 : capture 1\n00-01: Skip decoder mmap/I2S : Skip decoder mmap/I2S : playback 1 : capture 1\n00-02: Skip decoder deepbuffer/non pcm : Skip decoder deepbuffer/non pcm : playback 1\n00-03: With decoder/audio_aec_mix : With decoder/audio_aec_mix : playback 1 : capture 1\n00-04: rtk_snd_audio_v2_in : rtk_snd_audio_v2_in : playback 1 : capture 1\n00-05: rtk_snd_audio_v3_in : rtk_snd_audio_v3_in : playback 1\n00-06: rtk_snd_audio_v4_in : rtk_snd_audio_v4_in : playback 1\n00-07: rtk_snd_i2s_loopback_in : rtk_snd_i2s_loopback_in : playback 1 : capture 1\n00-08: rtk_snd_dmic_passthrough_in : rtk_snd_dmic_passthrough_in\n00-09: rtk_snd_pure_dmic_in : rtk_snd_pure_dmic_in : capture 1\n00-10: rtk_snd_btpcm_in : rtk_snd_btpcm_in : capture 1\n00-11: rtk_snd_btpcm_passthrough_in : rtk_snd_btpcm_passthrough_in : capture 1\n00-12: rtk_snd_btpcm_passthrough_out : rtk_snd_btpcm_passthrough_out : capture 1\n00-13: rtk_snd_ana_in_1 : rtk_snd_ana_in_1 : capture 1\n00-14: rtk_snd_ana_in_2 : rtk_snd_ana_in_2 : capture 1\n00-15: rtk_snd_tdm_in : rtk_snd_tdm_in : capture 1\n00-16: rtk_snd_spdif_in : rtk_snd_spdif_in : capture 1\n00-17: rtk_snd_i2s1_in : rtk_snd_i2s1_in : capture 1\n00-18: rtk_snd_i2s2_in : rtk_snd_i2s2_in : capture 1\n00-19: rtk_snd_tdm1_in : rtk_snd_tdm1_in : capture 1\n00-20: rtk_snd_tdm2_in : rtk_snd_tdm2_in : capture 1\n---\ncard0\ncard1\ncards\ndevices\nhwdep\npcm\nrtksndcompr\nrtksndhifi\ntimers\nversion" } ] }, { "role": "user", "content": [ { "type": "tool_result", "tool_use_id": "call_01_Q6r5J0YsmfdDKHkidHvD5509", "content": "cat: /proc/asound/card0/pcm*/info: No such file or directory" } ] }, { "role": "user", "content": [ { "type": "tool_result", "tool_use_id": "call_02_xHm2gaThzN2XwfnxkgNo6697", "content": "/vendor/bin/alsa_unit_test\n/vendor/bin/hw/android.hardware.audio.service\n/vendor/bin/hw/vendor.realtek.audioutil-service\n/vendor/etc/a2dp_audio_policy_configuration.xml\n/vendor/etc/audio\n/vendor/etc/audio/audio.primary.kent\n/vendor/etc/audio/audio.primary.kent.so\n/vendor/etc/audio/audio_hal_params.json\n/vendor/etc/audio_effects.xml\n/vendor/etc/audio_policy_configuration.xml\n/vendor/etc/audio_policy_engine_configuration.xml\n/vendor/etc/audio_policy_engine_default_stream_volumes.xml\n/vendor/etc/audio_policy_engine_product_strategies.xml\n/vendor/etc/audio_policy_engine_stream_volumes.xml\n/vendor/etc/audio_policy_volumes.xml\n/vendor/etc/car_audio_configuration.xml\n/vendor/etc/init/android.hardware.audio.service.rc\n/vendor/etc/init/vendor.realtek.audioutil-service.rc\n/vendor/etc/media_codecs_rtk_audio.xml\n/vendor/etc/media_codecs_rtk_audio_license.xml" } ] }, { "role": "assistant", "content": [ { "type": "thinking", "thinking": "This is gold!

But we also need to route the radio's analog audio through the mixer to an output.\n\nActually, let me think about this more carefully. The radio audio path is:\n1. Radio chip analog output → SoC ADC0 pins (Analog In1)\n2. SoC ADC digitizes the signal → ALSA capture PCM (pcmC0D13c)\n3. Audio HAL reads from PCM → routes to output bus\n\nIn a car audio system running Android Automotive with Car Audio HAL:\n- When a music app plays, it opens an output stream on `bus0_media_out`\n- The tuner input is a separate \"input source\" that gets mixed into an output stream\n- The audio HAL handles connecting the input to the output\n\nBut there's also the question of how the stream is started. For FM radio, the app would typically:\n1. Call `AudioManager.setParameters(\"TUNER_STATE=ON\")` or similar\n2. Or use the CarAudioManager to start the tuner input\n3. Or the HAL has its own mechanism\n\nThe fact that we're getting RDS data (station name, frequency) through the serial protocol but no audio suggests the ALSA/path configuration is what's missing. The MCU handles the control (tuning), but the audio path is separate.\n\nLet me also try the Audio Analog In1 Path with different values. The range is 0-3.

Remember the `Master Capture Switch` - that was for the INPUT (capture) path, not the output. The tinyplay played audio through the output path (pcmC0D0p), which uses the playback side.\n\nSo the good news is: the OUTPUT audio path works. The speakers are connected. Now the question is whether the INPUT (capture) path from the radio ADC gets routed to the output.\n\nAfter my mixer changes:\n- `Master Capture Switch = On On` - enable ADC capture\n- `Audio Analog In1 Path = 1` - set analog input mux\n\nBut there's a fundamental question: does the Android audio HAL route the FM Tuner input to the output bus? In a car audio architecture, the audio HAL needs to create a \"patch\" between the tuner input and an output. This is typically done through the CarAudioManager or through the audio HAL directly.\n\nActually, the simplest way to test is:\n1. After my mixer changes, tune to 94.7 FM using the radio demo\n2.

Let me think about this...\n\nThe output PCM device `pcmC0D0p` is \"Skip decoder normal/HDMI-RX\" - this might be the HDMI output or a digital output, not connected to the analog speakers. Let me check which PCM device actually routes to the speaker output.\n\nLet me look at the PCM devices again:\n- pcmC0D0p: Skip decoder normal/HDMI-RX - this is HDMI output!\n- pcmC0D1p: Skip decoder mmap/I2S - I2S output\n- pcmC0D2p: Skip decoder deepbuffer/non pcm - deep buffer output\n- pcmC0D3p: rtk_snd_audio_v2_in (has playback 1)\n- pcmC0D4p: rtk_snd_audio_v3_in (has playback 1)\n- pcmC0D5p: rtk_snd_audio_v4_in (has playback 1)\n- pcmC0D7p: rtk_snd_i2s_loopback_in (has playback 1)\n\nThe audio output to the car speakers should be going through one of the bus devices. In a car audio system with an external amplifier, the audio is typically sent via I2S or another interface to an external amp.\n\nThe car audio configuration shows bus outputs like `bus0_media_out`, `bus01_compress_media_out` etc. These are virtual devices in the Android Audio HAL that map to actual hardware outputs.\n\nLet me try playing through different PCM devices, particularly the ones that might connect to the actual speaker output.\n\nActually, I just realized - in a car audio system, the audio HAL creates virtual bus devices that apps output to. The tinyplay bypasses the Android Audio HAL and goes directly to ALSA. So tinyplay to pcmC0D0p (HDMI) wouldn't produce sound through the car speakers.\n\nThe way the car audio works:\n1. An app (like the radio demo or media player) sends audio to `bus0_media_out` via the Android AudioFlinger\n2. The audio HAL receives it and routes it to the actual hardware output\n3. The hardware output is typically an I2S DAC connected to an external amplifier\n\nSo my tinyplay test to pcmC0D0p (HDMI) wouldn't produce sound through the car speakers.\n\nI need to either:\n1.
