That’s unfortunate. It would have been nice if this had fixed it.

I CC Takashi, since he is the author of [1]. Maybe he can tell us if it
is related.

The only relevant(?) difference there is the following.

        $ diff -u alsa-info_2.6.32.9.log alsa-info_2.6.33_enable_msi.log
        […]

The only other thing I can think of is, that you go trough the commit
log yourself and try to figure out what changed regarding to your
chipset and CODEC.

And last not least you could try DebPkg:libasound2 from unstable and see
if this changes anything. Although I guess it will not.

Thanks,

Paul
