  • ALSA版本：

亲爱的朋友们，我不太熟悉ALSA，并pulseaudio感谢任何帮助：）如何修复耳机的麦克风并将其用作录音设备？

答案1

最后，我通过以下方法解决了耳机麦克风的问题：

amixer cset name='Differential Mux' lin1-rin1
amixer cset name="ADC Capture Volume" 192

我在这里的手册指南中找到了以下步骤orange pi 4 lts： https://uelectronics.com/wp-content/uploads/2022/08/OrangePi_4_LTS_User-manual_v2.1.pdf

现在我可以通过耳机麦克风录音：

arecord -d 5 -f cd test-mic.wav
