프로필 아래에는 output:analog-stereo우선순위 6000와 output:hdmi-stereo우선순위 가 있습니다 5400.
다음 명령을 실행하여 오디오가 작동하는지 확인하려고했습니다.
~을 위한output:hdmi-stereo
aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Right.wav
- 오디오 없음

그래서 기본값은 시뮬레이션된 스테레오라는 것을 알 수 있습니다. 그래서 다음과 같이 변경했습니다.

output:analog-stereo이 설정으로 플레이하는 이유는 우선순위가 더 높기 때문이 아닐까 싶습니다. 이상적으로는 둘 다 동일한 우선 순위로 실행되고 싶습니다. 이것은 내가 플레이하기 위해 했던 단계를 따를 필요가 없다는 것을 의미합니다 output:hdmi-stereo. 어쨌든 둘 다 플레이해야 해요. 일치하도록 우선순위를 변경해야 합니까 output:analog-stereo? 둘다 6000? 이 작업을 어떻게 수행합니까?
