나는 최근 GoBook XR-1 노트북에 Debian 8을 설치했습니다. Debian은 이를 Realtek ALC260 사운드 카드가 있는 것으로 감지합니다.
- Windows를 설치할 때 사운드 카드가 제대로 작동했습니다.
- 나는 이전에 Debian 7을 실행하는 동일한 노트북 모델을 가지고 있었고 다음 단계를 따른 후에 소리가 작동했습니다.아쿠분투. 이 단계는 Debian 8에서 실패하여 복구 모드에서 파일을 삭제할 때까지 Debian 8이 부팅되지 않았습니다.
을 사용하여 소리를 음소거 해제했습니다

노트북에서 사운드가 작동하도록 하려면 어떻게 해야 합니까?
답변1
코덱 덤프에 대한 간략한 설명 /proc: Intel HDA 코덱은 노드가 있는 그래프로 표시됩니다. Connection현재 노드에 대한 입력을 나열합니다. 예를 들어, 오디오 출력 노드는 0x02믹서 노드로 들어가고 , 이는 후면의 잭 에 연결되어야 하는 0x08핀 콤플렉스 노드로 들어갑니다 .0x0fline out
그러나 라인 출력 잭, 라인 입력 잭 및 마이크 잭에는 올바르게 레이블이 지정되어 있지만 노드의 "내부 라인 출력 모노, ATAPI"는 0x11가짜인 것 같습니다. GoBook XR-1의 제품 설명에는 내부 스피커가 2개 있다고 나와 있습니다. , 그래서 나는 "라인 출력"이 아닌 "스피커"가 있고 "ATAPI"가 없는 스테레오를 기대합니다. 그럼에도 불구하고 이것은 스피커로 지정된 노드입니다. 그러나 아마도 잘못된 노드일 것입니다.
따라서 일종의 이상한 수정이 필요합니다(스피커/헤드폰을 일부 노드에 할당하는 데는 몇 가지 이상한 점이 있습니다). ALSA 개발자에게 버그를 신고하고 코덱 정보와 오디오 카드의 하위 시스템 공급업체/ID( lspci -s 00:1b.0 -v -nn)를 제공합니다.
hdajackretask용기가 있다면 (Debian 패키지 ) 를 가지고 놀면서 alsa-tools-gui실제 스피커 핀 노드를 찾을 수 있는지 확인할 수 있습니다. (이렇게 하면 올바른 컨트롤이 다시 할당될지 확신할 수 없으므로 핀을 변경한 후에 항상 코덱을 살펴보십시오.)
하지만 드라이버 와 함께 작동했다는 점은 흥미롭습니다. snd_hda_codec_realtek올바른 구성을 읽는 다른 방법이 있을 수도 있습니다.
