Red Hat Bugzilla – Bug 283751
2.6.22 broke snd-hda-intel (worked on 2.6.20), model=auto solves it

Description of problem:
My sound card on a Toshiba A105 was working fine on a 2.6.20, but 2.6.22 broke
it. Google told me setting the module parameter "model=auto" would solve this,
and it did :)
Now the bug is, model=auto should be the default
Version-Release number of selected component (if applicable):
Advanced Linux Sound Architecture Driver Version 1.0.14 (Thu May 31 09:03:25
Steps to Reproduce:
1. Boot 22.214.171.124-45.fc6 (or previous 22 kernels)
2. Play any sound, it doesn't work!
alias snd-card-0 snd-hda-intel
options snd-card-0 model=auto
It's weird why model=auto is NOT the default, and it's boggling, what would be
the default for the module! One would imagine, it would be "auto", even alsa
docs says model=auto is the default, but obviously it is not!
Aha, so this is a bug in alsa-drivers. That should be fixed for all distros so
please file a bug at ALSA project (https://bugtrack.alsa-project.org/alsa-bug/)
and they should fix that in the new drivers release. Thanks.
