저는 Thinkpad T450s를 가지고 있으며 최근 XFCE를 사용하여 Debian Stretch로 업그레이드했습니다. Pavucontrol에는 세 개의 입력 장치가 있습니다.내장 마이크(연결되지 않음),마이크(연결되지 않음),기본 마이크(연결됨).
장치가 도크에 있을 때 모든 입력은 아무것도 등록하지 않는 것 같습니다. Pavucontrol의 파란색 막대에는 약간의 지터만 표시됩니다. Alsamixer를 사용하여 모든 채널의 음소거를 해제하고 볼륨을 50% 이상으로 높였습니다. 도움이 안돼.
이제 도크에서 장치를 놓으면 여전히 위의 세 가지 입력이 모두 표시되며 모두 오디오를 수신하는 것처럼 보입니다(이 역시 정확할 수 없음). 이는 도킹 스테이션과 관련이 있을 뿐만 아니라 PA가 일반적으로 입력 장치를 검색하는 방법과도 관련이 있음을 의미합니다.
pacmd list-cards도킹된 상태와 도킹 해제된 상태의 출력은 다릅니다.

그러니 무슨 일이 일어나고 있는 게 틀림없어요.
(이전 Ubuntu 설치에는 이 문제가 없었기 때문에 이것이 하드웨어 문제가 아니라고 확신합니다. 따라서 Pulseaudio/Alsa 구성에 문제가 있는 것 같습니다.)
이 문제를 해결하는 방법을 아는 사람이 있나요?
