No Audio on Android TV

[theguymadmax]

I have the same problem and it works again when I change the audio-setting in the ATV app to "downmix to stereo". Thank you for your help, TheDreadPirate.

Is there any way to force this setting on the server side so I do not have to tell my family to change it on every device?

And do you have any idea why the problem came all of a sudden?

What device are you using? Does it attempt to play but fail with error messages? Or does it transcode, producing FFmpeg logs but no audio? When you switch to downmix to stereo, it might be requesting a different codec, which would generate new FFmpeg logs. Clearly labeled logs are needed to see what is happening.
