Summary:                    FL is FL+FR and FR is FR+FL
Description: 
Card: Sound Blaster Live!
Chip: SigmaTel STAC9758/59

Between 1.0.5rc1 and 1.0.5a the Front Left and Front Right signals are
combined, which creates real crappy sound:

Front Left speaker = Front Left + Front Right
Front Right speaker = Front Right + Front Left

Checking the new "Surround Mix" in alsamixer gets even more confusing:

Front Left speaker = Front Left + Front Right + Center
Front Right speaker = Front Right + Front Left + LFE

There are no differences between the 1.0.5rc1 and 1.0.5a in the
proc/asound/card0/codec97#0/ac97#0-0+regs

Btw, the alsamixer options are getting really out of hand...
Eg a new option called just "Front" (I keep it off since I can't hear any
difference).

I think this AC97 codec problem.

Could you attach asound.state or amixer output.
And I think, that ac97 register were changed, but there are not in proc
output, because these are in diffrent pages.

OK, rechecked and the /proc-registers are set the same in 1.0.5rc1 and
1.0.5a. Installed 1.0.5a without loading the rc1 asound.state, and
handcrafted a new with alsamixer. Having set all options equal to rc1, the
asound.state file indeed shows some differences.

Uploading asound.state-1.0.5rc1, asound.state-1.0.5a and the diff
asound.state-diff-1.0.5rc1-1.0.5a
