First check /proc/asound/cards to see whether the emu10k1 model is
detected properly.  If '[Unknown]' is shown, your model is not
listed in the whitelist.

There was a bug that the front control conflicts with ac97 and emu10k1
dsp which was already fixed in the latest version (at least on
2.6.16-rc3).

For what it is worth, I had issues with my SB Live! but as this all
(appeared) to start when my CPU died and I had to reset BIOS or if I
did indeed move up to 2.6.15 at around the same time I can't remember
(2.6.15 release and CPU died all around same date) - refer to the
following:

http://lkml.org/lkml/2006/2/11/4

As stated the solution for me was to update alsa-utils and alsa-libs
which fixed the issues I was getting - I found that if one of the
'controls' (15, I think?) was invalid at boot, all the volume settings
in alsamixer got set to '0' (i.e. mute/turned off) - no sound.

Such a problem is usually because of init script rather alsa-lib
version.  It should call alsactl with -F option.

I would agree - but I only have one asound.state file, and also doing
the upgrade to said alsa utils and libs *fixed* it...

On my system at least something was going awry.
