USB를 통해 Gentoo Linux에 연결된 태블릿 마이크를 사용하여 소리를 녹음할 수 없습니다.
설정을 확인해보니 USB 마이크가 감지되었습니다.
arecord --list-devices

그래서 나는 추측한다
arecord -D hw:2,0 -d 5 test.wav
나에게 녹음을 제공하지만 결과는 다음과 같습니다.
arecord: main:722: audio open error: Device or resource busy
이 문제의 원인을 찾는 방법을 아시나요? 아니면 내가 잘못된 길로 가고 있는 걸까? asound.conf에 특수 항목을 추가해야 합니까?
현재는 다음과 같습니다.
cat /etc/asound.conf
#input device
pcm.AD1989A_inputs {
type multi
slaves.a.pcm "hw:PCH,0,0"
slaves.a.channels 2
slaves.b.pcm "hw:PCH,0,1"
slaves.b.channels 2
bindings.0.slave a
bindings.0.channel 0
bindings.1.slave a
bindings.1.channel 1
bindings.2.slave b
bindings.2.channel 0
bindings.3.slave b
bindings.3.channel 1
}
어쩌면 pcm 목록도 솔루션과 관련이 있을 수 있습니다. 그래서 여기에 추가합니다.
