지난 며칠 동안 나는 alsaplayer를 계속해서 재생시키는 습관을 들였습니다. 일단 얼면 멈추고, 깨어나면 다시 시작됩니다...여러 번. 지난번에는 회복되지 않았습니다. dmesg는 snd_hda_intel 연속 페이지 폴트를 표시합니다. alsaplayer를 죽이는 것은 도움이 되지 않습니다. 새로운 alsaplayer 인스턴스가 시작되지 않고 /tmp/alsaplayer_ale내 소켓의 첫 번째 응답을 기다리는 동안 차단되었습니다. 커널 모듈을 제거할 수 없습니다. 다시 시작해야했습니다.
펄스 오디오가 없습니다.
정지하려면 먼저 실행 xscreensaver-command -lock한 다음 pm-hibernate. 에서 정지하기 전에 dhcpclient 임대를 해제하는 방법을 배웠습니다 /etc/pm/sleep.d. 오디오 채널을 플러시하는 것과 비슷한 작업을 수행해야 한다고 생각하지만 이를 구현하는 방법을 모르겠습니다. 어떤 팁이 있나요?
편집하다 몇 가지 로그를 추가했습니다. 목적은 커널을 디버깅하는 것이 아니라 재생을 완전히 중지하는 프로세스를 식별하는 것입니다. 원격 스트리밍의 경우 더 깔끔하게 종료하고 재개할 수 있도록 사운드 버퍼도 플러시해야 합니다.
