음소거될 때까지 몇 초 내에 오디오가 사라집니다.

드라이버를 ALC294실행하는 장치에서 소리를 재생할 때마다 2초 이내에 소리가 사라집니다. snd-hda-intel문제는 설명된 것과 정확히 동일합니다.여기. Windows에서는 모든 것이 잘 작동하며 ChromeCast를 통해 Chrome 탭을 미러링해도 소리가 납니다. 아직도 달리는 aplay -D plughw:0,1 /usr/share/sounds/alsa/Front_Center.wav소리 가 들려

나는 /etc/modprobe.d/alsa-base.conf다음과 같은 다양한 옵션을 시도했습니다.이것

이

options snd-hda-intel power_save=10 power_save_controller=N model=ref

그리고pulseaudio에서 타이머 기반 일정 비활성화, 모두 성공하지 못했습니다.

내 시스템의 일부 출력은 다음과 같습니다.

이것이 문제인가 alsa, 아니면 pulseaudio문제인가?

답변1

해결책은 아니지만 문제에 대한 설명과 해결 방법을 찾았습니다.여기: 이 문제는 Windows 10에서 Linux로 재부팅한 후에만 발생합니다. Windows가 스피커를 절전 모드로 전환한 것으로 보이며 Linux가 스피커를 제대로 깨울 수 없습니다. 해결 방법은 Windows를 완전히 종료하고 Linux로 부팅하는 것입니다.
