Bug#532613: Possible cause?

[MP <singularita@gmail.com>]

I upgraded from 2.6.26 to 2.6.30-1-amd64 kernel (debian unstable) and
I also found out my sound levels are ridiculously low when volume
maxed to 100%.

However I searched for solution and I have found a workaround:

In alsamixer, if you scroll to the right, there are four sliders "Via
DXS" - in my case they were all on zero. Once I put them all to 100%,
volume levels returned back to reasonable values (same as before the
bug).

So I guess these four DXS levels are probably incorrectly rememebered
or incorrectly reset.

Try raising these Via DXS sliders as a workaround till this is fixed properly.
