이것은 pulseaudio에 문제가있는 것 같습니다. 전화기에서 VNC를 통해 로그인 한 후 비디오 재생을 시작하여 X가 충돌하는 경우가있었습니다. 다시 시작했는데 갑자기 소리가 나지 않습니다.
Intel HDA / Realtek ALC889가 있습니다
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
alsamixer
이것을 잘 감지하고 있습니다.- PulseAudio는이 alsa 장치를 감지하지 못하므로
auto_null
기본 싱크 (아래 로그)로 사용하고 있습니다. - PulseAudio를 올바르게 종료하면 (자동 시작하지 말라고) 직접 ALSA와 사운드 카드의 통신이 제대로 작동합니다.
speaker-test
예를 들어 작동합니다. 따라서 하드웨어 및 ALSA 계층은 훌륭한 IMO입니다. - 로그에서 카드가 "통화 중"인 것처럼 보이지만 실제로는 왜 또는 왜 지금인지 알 수 없습니다. 충돌로 인해 ALSA 잠금 파일이 여전히 존재합니까?
방금 달려서
sudo fuser /dev/snd/*
이것을 보았습니다.oli@bert:~$ sudo fuser /dev/snd/* /dev/snd/controlC0: 1884 /dev/snd/pcmC0D0c: 1884m /dev/snd/timer: 1884
프로세스 목록 (
ps aux | grep 1884
)을 보면 프로세스 1884가임을 알 수arecord -c 1 -f S16_LE -r 8000 -t raw
있습니다. 이것이 무엇인지 왜 실행 중인지 잘 모릅니다.arecord
루트로 시도하고 죽이면 하드웨어에서 다시 생성되고 리 바인드됩니다.
나는 무슨 일이 일어나고 있는지 알지 못하고 알아내는 방법을 모르는 매우 성가신 상황에 처해 있습니다. 이 작업을 다시 수행하기 위해 모든 제안을 할 수 있습니다. 불을 끄십시오.
그리고 PA 자동 로딩을 중단하고 종료 한 다음로 시작하면 얻을 수 있습니다 -vvvv
