Bugs 483271 and 483594 may be similar/related:
* Bug 483271 -  Sound only partially working on <edited> (Intel Q43)  
* Bug 483594 -  FEAT: RHEL 5.4 - update ALSA HDA audio driver from upstream
Comment 3 Jaroslav Kysela 2009-03-10 12:00:06 EDT
Please, test kernel (HDA update) from bug#483594 . Also, attach output from
'alsa-info.sh --no-upload' when mentioned kernel does not work as expected.
Comment 4 Larry Troan 2009-03-16 14:02:04 EDT
Per bug 483594....
Third test kernel is available here:


It should solve issues with module unloading (reboot oops/panic problems) and
enables PC Beep on ALC662/663 codecs.  

Please test and report results back here. Also, please attach output from "alsa-info.sh --no-upload" if test kernel does not work as expected.

Setting bug to NEEDINFO (reporter).

Please, try to add 'options snd-hda-intel model=laptop' to your /etc/modprobe.d/sound (or /etc/modprobe.conf). Leave all other options if line options snd-hda-intel exists in this file.

Also, you may try to test another models:

  6stack-dig    ditto with SPDIF
  3stack        3-jack
