Summary:                    Left front channel always muted on boot
Description: 
ice1724 (M Audio Revolution 7.1 in my case) always restores the mixer
settings at boot, but the left front channel is muted regardless.  The fix
is to run alsamixer and adjust the slider again.  This forces the channel
to unmute.  Should I be worried "amixer scontrols" reports everything as
"Mono" as well?

Well, I have the muting problem too (M-audio Revolution 7.1). In most cases
it is indeed the left channel that stays muted. In my case it seems that
the first channel that is tried to be unmuted, whichever it is, remains
silent although the new volume value is set in the mixer. 

When I boot up my computer (with alsa volume restore script disabled) and
try to unmute the left channel first with amixer cset numid=20 40, that
channel remains silent (although the new value is reported by the mixer).
When I do the right channel first (numid=21), the same is true for the
right one. The second change of volume always works, whether it is the
same channel as the first one or another (providing you really change it,
to a different value, not the same).

So the very first change of volume seems to be the problem (at least in my
case).

Note: I haven't tested it with the rear channels, as I don't use them
(headphones) :).
