我遇到一个问题。我将立体声耳机/麦克风插孔插入笔记本电脑上的 4 针 3.5 毫米 (TRRS) 插孔。耳机立体声正常工作，但耳机麦克风不工作。笔记本电脑内置麦克风正在工作。
| 硬件软件 | 姓名 |
|---|---|
| 操作系统 | Ubuntu 22.04（Windows 11 双启动） |
| 笔记本电脑品牌和型号 | 华硕UX3402ZA |
| 声卡 | 软HDADSP |
| 音频芯片组 | 瑞昱ALC294 |
| 耳机和麦克风 | Sennheiser GSP 302（是的，它适用于 Windows） |
注意：我之前必须使用以下方法修复在内置扬声器上不起作用的输出声音这个补丁。除了来自内置组合插孔的麦克风输入之外，所有与音频相关的功能都运行良好。内置麦克风也可以正常工作。
脉冲音频
我评论了以下内容等/脉冲/default.pa由于“耳机立体声麦克风”源状态已暂停；挂起原因：IDLE。
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
脉冲音频根据以下内容识别组合插孔的输入：
- 索引 4：组合插孔的输入（不工作）
- 索引 5：内置麦克风（工作中）

Pavucontrol 也显示该设备，但未检测到输入。
阿尔萨
Alsa 应该捕获“HDA Analog 0”下组合插孔麦克风的输出，但没有捕获。
我尝试更新编解码器/etc/modprobe.d/alsa-base.conf一一使用以下选项，我没有将它们组合起来。插入组合插孔的耳机继续工作，但仍然没有检测到输入。
#options snd-hda-intel model=asus-zenbook
#options snd-hda-intel model=dell-headset-multi
#options snd-hda-intel model=aspire-headset-mic
HDAJack重任务
Realtek ALC294 上的 HdaJackRetask 仅显示 2 个引脚已连接：
- ID 0x17：内部扬声器
- ID 0x21：黑色耳机，右侧（但立体声正常工作）
“内置麦克风”和“耳机麦克风”都没有连接的引脚。 （请记住，内部麦克风正在工作）。
以下未连接的引脚显示“麦克风”选项：
- ID 0x19
- ID 0x1a
- ID 0x1b
我尝试覆盖（理解“安装引导覆盖”）以下内容：
- 0x19（单独）
- 0x1a 和 0x1b
重新启动后，重新打开 HDAJackRetask 不会将它们显示为已连接。我敢打赌它有问题，但我不能说。
欢迎任何提示，我已经花了好几天的时间来解决这个问题。
我认为问题来自Alsa，因为pulseaudio似乎可以识别并运行组合插孔的输入（显示在pavucontrol中），但Alsa不能（不显示在alsamixer中）。
感谢您的时间 ！
