On my (headless) Linux box at home, I have a soundcard with digital out
(optical), going straight to my amp. I can use various music-playing
servers to let me select the music to play remotely, with the output
emitting from the server.
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.
I wondered if the issue was with PulseAudio for a long time, but the
problem still occurs after reconfiguring things to go direct to ALSA.
As a work-around, I could modify the open-source software I'm using, to get
it to run an unmute command after starting to play a track, but that's
ridiculous. Surely there's a way to just stop it auto-muting on close?
I don't suppose anyone else has ever encountered this, or found a solution?

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.

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.

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)

If pa is around, it presents itself as an alsa card - probably card 0.
Telling a client to use alsa on a pa system will PROBABLY result in
alsa -> pa -> alsa
not
alsa
...unless you also specify card 1.
See /proc/asound/cards.
