Ah, sorry, perhaps I wasn't clear. When I said "I can use several different music players to play music remotely", I meant that I had in fact tried several, all with the same problem.

The problem even occurs if I use ALSA's own "aplay", like so:

$ amixer -c 1 sget IEC958
Simple mixer control 'IEC958',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [on]

$ aplay -D iec958:CARD=1 sample.wav
Playing WAVE 'sample.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

# Or aplay -D hw:CARD=PCH,DEV=1

$ amixer -c 1 sget IEC958
Simple mixer control 'IEC958',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [off]


Although hah, I just ran through that process again and the second time the On setting stuck.

Which I think I've seen happen before, but it always seems to go back to flipping off afterwards.

are you sure it's ALSA itself and not whatever program you're using
to play the songs?

maybe try some different audio players to see if the same thing happens.
