Looking at this issue again, I notice that even if I'm telling aplay to use a direct ALSA hardware device, pulseaudio's daemon still starts up in the background. Grr. I've purged pulseaudio from the system entirely now, so will see if that has an effect.. even though it wasn't meant to be being used. (Pulseaudio has normally been great, in my experience, but I don't like that it seems to be starting up even when unintended) On Wed, 23 Sep 2015 at 18:13 Toby Corkindale <toby@dryft.net> wrote:
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.

However for reasons that completely elude me, the ALSA system auto-mutes the output at the end of every song. It's infuriating. ALSA does indeed have an "auto-mute" setting, but I have ensured it is set to off.
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.
