이것이 제가 지금 막힌 부분입니다. alsa-base포장되어 있어야 한다고 생각했는데 지금은 사용할 수 없는 것 같습니다.
마침내 alsamixer괜찮은 것 같았습니다.

답변1
"alsa는 더 이상 사용되지 않습니다"라고 말하는 사람들은 잘못된 것입니다. Pulseaudio는 ALSA 위에서 실행되는 사운드 데몬입니다. ALSA는 여전히 그 뒤에 존재합니다.
그러나 실제로 문제는 펄스 오디오로 인한 것일 수 있습니다. pavucontrol을 열고 옵션을 수정하면 도움이 될 수 있습니다.
답변2
알사는 버려졌습니다. 요즘 대부분의 배포판(Debian 포함)은 pulseaudio사운드 관리에 의존합니다.
시스템에서 펄스 오디오가 실행되고 있습니까? 그렇다면 이것이 문제의 근본 원인일 수 있습니다. 어쨌든 alsa는 잊어버리고 pulseaudio와 그 믹서를 사용하는 것이 좋습니다( pavucontrol아주 좋습니다). 여기에는 configuration출력을 선택할 수 있는 탭이 있습니다 .
내 노트북에서는 pulseaudio가 기본적으로 HDMI 출력으로 사운드를 보냅니다.
