Public bug reported:

Upon boot, the EMU20K2's PCM input channel is enabled (unmuted), but it
shows as disabled (muted) in alsamixer.  One has to enable it and
disable it in alsamixer in order to ensure sound does not "leak" out.

This is unaffected by alsactl store/restore - even if the asound.state
file includes information explicitly turning the PCM input off, alsactl
restore fails to automatically fix the issue.  One must manually go in
and turn PCM input on, then off, to ensure it's really off.

This has been the case for a few Ubuntu releases now. I'm reporting it
precisely because it seems it's not been reported (or at least, not
getting attention).

** Attachment added: "Alsa stored state.  Even using this state will not cause 
the EMU20K2 chip to turn off its PCM input automatically."
