멍청한 질문이라 죄송합니다. 헤드셋에 문제가 있어서 한동안 답변을 찾고 있었는데 소용이 없었습니다.
헤드셋이 자동으로 노트북에 연결되면(예: 헤드셋을 켰는데 노트북이 이미 실행 중인 경우) 사운드가 "모노"로 설정됩니다. 전체 블루투스 서비스를 다시 시작하면 같은 일이 발생합니다.
sudo service bluetooth restart
헤드셋 연결을 끊었다가 (GUI에서) 수동으로 다시 연결하면 스테레오와 기본적으로 설정된 높은 충실도에서 잘 작동합니다.
나는 다음을 시도했다저것이 명령의 출력이 도움이 될 수도 있습니다. 연결 상태가 좋지 않은 경우:
journalctl -f

답변1
해결 방법으로 다음을 사용할 수 있습니다.
- 설치하다
bluetoothctl sudo bluetoothctl- 결과는 다음과 같습니다.
# paired-devices
Device CB:B2:CG:26:FD:80 <DEVICE_1_NAME>
Device 70:26:03:89:03:B8 <DEVICE_2_NAME>
- "device"와 장치 이름 사이에 문자열을 복사합니다(예: 70:26:03:89:03:B8).
- 다음 스크립트에 붙여넣으세요.
sudo bluetoothctl << ANSWERS
disconnect 70:26:03:89:03:B8
ANSWERS
sleep 5s
sudo bluetoothctl << ANSWERS
connect 70:26:03:89:03:B8
ANSWERS
장치를 다시 연결해야 합니다.
중간에 있는 수면은 운전자가 연결 해제를 완료하는 것입니다(그렇지 않으면 오류가 발생합니다).
도움이 되었기를 바랍니다 :)
