Maybe you had the same problem I did...

There is a problem with ALSA where the computer tries to play digital
and analog sound at the same time for some hardware.  When it fails,
it disables analog playback over SPDIF.

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/25632

Basically, I have a scripts that just runs "iecset audio on" to
restore sound.  (I usually have to close the frontend and then run the
script.)

Good luck,
Patrick
