전면 헤드폰 잭과 후면 헤드폰 잭에 헤드폰을 연결해 보았는데, 둘 다 사운드 재생 시 소음이 많이 발생했습니다. 유휴 상태로 돌아오자 소음이 멈췄습니다.
답변1
부분 답변:
표준 Intel HDA 사운드 컨트롤러가 있습니다. 여기에는 Creative CA0132 코덱 칩(코덱 = 인코더/디코더)이 연결되어 있습니다. 칩은 약간 특이한 것처럼 보이며 ALSA에는 이미 다른 코덱에서는 볼 수 없는 많은 기능이 있습니다.
이 칩에 대한 Google 검색에서 발견되었습니다.이것, 커널의 코덱 드라이버가 아직 많이 개발 중인 것 같습니다.
따라서 첫 번째 단계는 배포판에서 허용하는 최신 커널을 설치하는 것입니다. 어쩌면 이것이 문제를 해결했을 수도 있습니다.
그렇지 않은 경우 최신 커널 소스를 사용할 수 있는지 확인하십시오.여기, 소스에서 배포판에 커널을 컴파일하고 설치하는 방법을 알아보세요. (어렵지 않습니다. 모든 배포판에 사용할 수 있는 튜토리얼이 많이 있습니다.)여기CA0132 코덱 드라이버의 변경 사항에 대한 로그 목록입니다.
그래도 도움이 되지 않는다면, (원하는 경우) 코덱 내부에서 무슨 일이 일어나고 있는지 디버깅을 시작할 때입니다.
HDA 코덱은 DAC, 믹서 등에 해당하는 노드로 그래픽으로 구성되어 있으며, 시끄러운 백색 잡음은 코덱을 통과하는 사운드의 경로에서 일부는 실제 사운드를 생성하지 않음을 의미합니다. 또한 너무 많이 증폭되어 익사할 수도 있습니다. 실제 신호가 나가거나 실제 신호가 예상되는 위치에 도달하지 않기 때문입니다.
여기서 첫 번째 단계는 ALSA에서 믹서 설정을 사용하는 것입니다. 필요한 경우 Pulseaudio를 비활성화하여 제외하십시오(Pulseaudio가 예측할 수 없는 방식으로 ALSA 믹서 설정을 인계받기 때문입니다). 직접 소리를 재생합니다 aplay. 귀하의 질문에 있는 정보에 따르면 이미 이 작업을 수행했을 수도 있고 Pulseaudio가 설치되어 있지 않을 수도 있습니다.
모든 캡처 믹서는 음소거된 것처럼 보이지만, ALSA에서 볼 수 없는 일부 노드를 통해 루프백하는 경우를 대비해 모든 캡처 및 특수 기능 믹서의 볼륨도 낮아졌습니다.
그런 다음 어떤 재생 믹서가 백색 소음의 볼륨에 영향을 미치고 어떤 믹서가 그렇지 않은지 알아보세요.
운이 좋아서 실제 신호가 사라진다면 아마도 뭔가를 들어본 적이 있을 것입니다. 그렇지 않은 경우 코덱 구성(또는 이와 유사한 구성)을 살펴보아야 하며 /proc/asound/card0/codec#0, 드라이버에 이상한 점이 필요할 수도 있으므로 해당 드라이버에 대한 커널 버그 추적기에 버그를 제출할 때입니다.
