Public bug reported:
In the latest update of Ubuntu 12.10, alsa stopped working properly on my:
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio
Controller
I have always had some issues with SPDIF out as described elsewhere, but
now I can't connect to it at all. All of the volume settings appear to
be correct, pulseaudio is running fine, and I can't see anywhere that
could be an incorrect configuration.
When I try to play a file directly to the alsa driver with:
mplayer -ao alsa
it reports back that the connection was refused. This behavior persisted with
sudo as well, so not a permissions error.
I tried using:
alsa force-reload
to reload the alsa driver, which did not change the behavior, regardless of
whether I restarted pulseaudio.
When I try to play a file directly to the iec958 port on the sound card with:
mplayer -ao alsa:iec958
it reports "Failed to initialize audio driver 'alsa:iec958'"
The only things I can think of are a bug in the audio subsystem, a bug
in the alsa driver in the latest kernel update (3.5.0-11 versus 3.5.0-10
where it was working fine), a sudden inexplicable hardware failure, or
some kind of user error that I'm unable to find. Given that I've been
able to easily get this working plenty of times previously, I hope that
it is not user error only.
