I would suggest you start checking back through the changelogs between 
kernel-2.6.18-194.el5 and kernel-2.6.18-164.el5, find likely candidates 
that may have caused your issue and then rebuild a testing kernel with 
that patch reverted. If that testing kernel fixes your issue then you've 
identified the issue and can file a bug report upstream.

To start you on your way, this patch looks like a likely candidate for 
you to investigate further:

* Mon Dec 21 2009 Jarod Wilson <jarod@xxxxxxxxxx> [2.6.18-183.el5]
- [sound] alsa hda driver update for rhel5.5 (Jaroslav Kysela) [525390]
