나는 hdmi를 통해 tx-sr608 앰프에 연결된 음악을 재생하는 htpc를 가지고 있으며 이 앰프는 hdmi를 통해 프로젝터에도 연결되어 있습니다.
HTPC <-> TX-SR608 <-> TV
프로젝터가 켜져 있을 때, 전원을 끌 때 또는 전원을 모두 켜지 않은 경우, 일반적으로 7~10분 사이에 임의의 시간이 지난 후 pulseaudio가 ELD 정보가 비어 있는 것에 대해 불평하고(아래 참조) 스위치를 전환합니다. 가라앉고 더 이상 오디오가 들리지 않습니다.

그 글을 읽은 후 dpm을 끄려고 했습니다.버그 보고서
module-suspens-on-idle 및/또는 module-switch-on-port-available을 비활성화하려고 했습니다.
아무 일도 일어나지 않는 동안 싱크대가 떨어지는 이유를 찾는 데 어려움을 겪고 있습니다. 앰프의 전원을 끄거나 켜면 싱크가 다시 작동합니다.
