At this state, run "alsactl store", and keep the renewed asound.state file. Once when this happens again, just run like alsactl -f /your/saved/asound.state store to restore the status. > Unfortunately the fix isn't permanent because after reboot I cannot > get regular sound via spdif until I have once played a file with 5.1 > audio track. This is unlikely a kernel issue but the user-space issue. I guess this was triggered because of changes of the id numbers in mixer elements. Some user-space program (e.g. kmix) tend to restore the mixer setup forcibly but often wrongly.
