Ubuntu 20.04 Bluetooth 헤드폰은 내부 스피커를 통해 재생됩니다.
Aug 17 2020
Skullcandy Crusher Wireless 헤드폰을 컴퓨터에 페어링하려고합니다. 페어링하고 사운드 메뉴에서 성공적으로 선택할 수 있지만 어떤 이유로 오디오가 여전히 내부 스피커를 통해 재생됩니까?
I에 설명 된 수정 시도 477,933을 하며https://www.nielsvandermolen.com/bluetooth-headphones-ubuntu/ 아무 소용이 없다
내 설정 메뉴는 다음과 같습니다.
아무도 이것을 고치는 방법을 알고 있습니까?

내가 들어갔을 때 alsamixer내 헤드폰이 음소거되어 있음을 보여 주었으므로 위의 SO 질문에 표시된 것처럼 음소거를 해제했지만 도움이되지 않았습니다.

헤드폰은 음소거되지 않았으며 출력 볼륨은 100 %입니다.
내가 실행하면
aplay /usr/share/sounds/alsa/Front_Center.wav소리가 헤드폰에서 나옵니다! 그러나 설정 메뉴로 돌아가서test스피커를 사용해 보거나 Firefox를 통해 음악을 재생하면 사운드가 여전히 내부 스피커에서 나옵니다.나머지 단계는 정상적으로 나왔습니다.
aplay -l목록을 사용할 때 헤드폰이 오디오 싱크로 포함되지 않는다는 점을 제외하면 중요 할 수 있습니다. 모르겠어요.
다음은 가이드에 해당하는 명령의 출력입니다.

먼저 사용자 계정에 대한 새로운 pulseaudio 구성을 재 구축하는 것이 좋습니다 . 이것은 대부분의 경우 문제를 해결하거나 적어도 pulseaudio 구성과 관련된 문제를 배제 할 수 있습니다.
이전 pulseaudio구성 파일은 때때로 pulseaudio패키지 업그레이드 후의 최신 버전과 충돌 할 수 있습니다 . 이 문제를 해결하려면 다음 단계를 따르십시오.
터미널에서 다음 명령을 실행하여
~/.config/pulse/구성 디렉토리를 백업~/.config/pulse_old/하십시오.mv ~/.config/pulse/ ~/.config/pulse_old/그 후 시스템을 재부팅하여 새
pulseaudio구성 파일을 작성하십시오. 새~/.config/pulse/디렉토리가 자동으로 생성됩니다.지금 오디오를 테스트하십시오.
어떻게 든 경우 이 수정 프로그램을 적용한 후 수정 프로그램을 적용하기 전에 이전 상태로 되돌아 가기로 결정, 다음 단계를 따르십시오
터미널에서 다음 명령을 실행하십시오.
rm -r ~/.config/pulse/터미널에서 다음 명령을 실행하십시오.
mv ~/.config/pulse_old/ ~/.config/pulse/시스템을 재부팅하십시오.
그러나 모든 것이 정상이고 문제가 해결 된 ~/.config/pulse_old/경우 터미널에서 다음 명령을 실행하여 백업 된 이전 구성 디렉토리 를 제거하여 여유 공간을 확보 할 수 있습니다 (원하는 경우).
rm -r ~/.config/pulse_old/

한 번 Windows 와 Linux 에서 비슷한 문제가 발생 했으며 두 시스템의 솔루션 은 헤드셋 마이크 를 비활성화하는 것이 었습니다 (내부 마이크 선택).
블루투스 인터페이스가 다음 중 하나만 지원하는 것 같습니다 (여기에서 논의).
- 고품질 (a2dp) 오디오 출력 또는
- 고품질 (a2dp) 마이크 입력 또는
- 저품질 (hsp / hfp) 입력 및 출력.
헤드셋 마이크가 고품질로 캡처하여 헤드셋 스피커를 차단하는 경우 일 수 있습니다.
