Ubuntu Eoan이 설치된 노트북이 있습니다. 단일 사운드 카드, 단일 헤드폰 잭.
노트북 스피커와 헤드폰을 동시에 사용하고 싶은데(특별한 이유는 없고 그냥 그렇습니다) 헤드폰을 연결하자마자 스피커를 사용할 수 없게 됩니다.
동시 출력을 활성화하고 -switch-on-connect 및 -switch-on-port-available 모듈을 제거하고 더미 수신기를 생성하려고 시도했지만 아무것도 작동하지 않았습니다. Google 검색에서는 반대 문제인 인간 문제만 반환됩니다.아니요스피커와 헤드폰이 동시에 재생되기를 원합니다.
누구든지 해결책이 있습니까?

ALSA에서 이 설정을 통해 헤드폰을 연결하면 스피커가 음소거됩니다.

이것을 다음으로 변경하십시오.장애가 있는

시스템이 복원될 때 ALSA가 설정을 유지하도록 ALSA 설정을 저장합니다.
