[alsa-devel] Fwd: No sound with ATI SB450

[Ben DiDonc]

Takashi,
I did try passing model=auto to all 14 release candidates, but without
success. the codec is never detected (see my previous posts for
alsa-info.sh outputs with both 2.6.20 and 2.6.17).
My problem is I cant get my sound card to work with kernel 2.6.20,
when it used to work with 2.6.17.
