Stereo through digital output fails

[Slick]

After operating Mythbuntu 8.10 for some time audio stops working for non-AC3 audio from MP3s and Firefox.

TV audio works regardless but the tuner card was installed after the audio failed. After looking throughout the mythbuntu thread in www.ubuntuforums.org I found this thread (http://ubuntuforums.org/showthread.php?t=991219&highlight=digital+stereo). I used the fixed mentioned in that thread and it worked for me, MP3s now play. That fix is as follows:

sudo mv /etc/init.d/alsa-utils /etc/init.d/alsa-utils.old
"reboot"
sudo mv /etc/init.d/alsa-utils.old /etc/init.d/alsa-utils
alsamixer
"Then reset the volume levels on your sound card as everything will be muted."
sudo alsactl store

I don't understand the problem and I cannot cause the failure on command but will have to wait for it to fail again.

My audio card is:
 Multimedia audio controller: Creative Labs SB Audigy LS

Thank you for helping to improve Mythbuntu by reporting this issue.

Unfortunately the developers do not have this equipment to reproduce the issue, so we need to ask one or more of you, preferably someone running auto-builds (http://www.mythbuntu.org/auto-builds), to please attach your backend log to this ticket. Logs from more than one person are welcome.

It would be helpful if it was not the whole log, but rather starting from a few entries before changing the channel (full verbose logs from startup can be painful to sort through).

For these logs to be truly useful, they need to have some extra verbose options enabled (-v record,channel,siparser) on the backend command line.
