나는 Intel 칩셋을 사용하는 iMac(2013년 후반부터)에 Debian을 설치했습니다. 현재 시스템 설치 후 발생할 수 있는 사운드 문제를 해결하려고 노력 중입니다. 소리는 재생되지만 가끔 스피커에서 딱딱거리는 소리가 들립니다. 예를 들어 시작할 때, 종료할 때, Audacity(문제를 발견한 후 설치한)를 열 때 등이 있습니다. 게다가 음악을 틀면 음질이 좋지 않고, 싸구려 라디오나 낡은 자동차 스피커(또는 압축률이 낮음)처럼 들립니다. 이 iMac에도 설치되어 있는 MacOS로 부팅하면 음질이 훨씬 좋아집니다. 오디오 장비는 다음과 같습니다.8 시리즈/C220 시리즈 칩셋 HD 오디오 컨트롤러
최신 커널 5.15(백포트에서)를 설치하려고 시도했지만 Timeshift를 사용하여 이전 5.10(안정적 저장소에서)으로 돌아왔습니다. 문제는 여전히 존재합니다. 커널을 업데이트해도 문제가 해결되지 않았습니다. 이 PulseAudio 페이지에서 모든 솔루션을 시도했습니다.https://wiki.ubuntu.com/Audio/PositionReporting그러나 결과가 없습니다.
이 문제는 오래 전부터 있었던 것 같습니다. 그러나 나는 어떤 해결책도 찾을 수 없습니다.
