Clarification: I normally physically log on to and play media on host A using mpv, displaying the video on an external monitor HDMI-A-2 and playing the audio from host A’s headphone jack connected to external speakers. Today, I tried not physically logging on to host A, but remotely logging in from host B (my phone) using ssh from the same network and running the mpv command from host B. mpv then displays the video on the expected display HDMI-A-2, but it doesn’t play any audio.

Symptomatically, if I haven’t logged on physically to host A, mpv only displays video, plays no audio and throws errors. Why do I need to be physically logged on to host A for mpv to be able to access audio? You’d think a video feed would be more guarded than an audio one. But maybe this isn’t about security at all? Please enlighten me! 😊

    You can see from the errors that mpv is unable to find your sound card so it won’t play any sound not just movies played over ssh

      That is not it. It throws no errors whatsoever if I run mpv directly from the host. I believe it to be a permissions related matter and that mpv somehow knows how to work around video but not audio. Tomorrow I’ll try to add my user to the pipewire and audio groups and see what that does.
