Ubuntu 15.04에서 S/PDIF 및 HDMI 오디오가 작동하는 데 문제가 있습니다.
"시스템 설정 > 사운드"에 S/PDIF 출력이 표시되지만 사운드가 출력되지 않습니다. HDMI 출력이 표시되지 않습니다.
1단계의 명령을 실행해 보았습니다.https://help.ubuntu.com/community/SoundTroubleshootingProcedure, 그러나 문제가 해결되지는 않습니다.
다음은 alsa-info.sh 스크립트의 출력입니다.http://www.alsa-project.org/db/?f=76f5134bf711a2727fa56d1d7ec582945fc6944c
출력은 다음과 같습니다 aplay -l.

내가 달릴 때 aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav, 나는 얻는다.
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
그러나 실제로는 소리가 재생되지 않습니다. 카드 0의 장치 7과 8, 카드 1의 장치 1에서도 마찬가지입니다.
여기서 어디로 갈 수 있는지 아이디어가 있나요?
