The commit that Stefan is referring to is
http://git.alsa-project.org/?p=alsa-
kernel.git;a=commit;h=878a4f521bfe83c49694ac990058080fbe090812
already at Karmic's kernel.
** Description changed:
- Sound worked without further configuration on Ubuntu 8.10. With Ubuntu
- 9.04 (also with recent Suse and Fedora versions) I had to add a model
- parameter to the modprobe.d/*.conf file. I used model=5stack and was
- happy with sound an 9.04. The current karmic version gives me no sound
- on the internal speakers for all configurations I tried (3stack, 5stack,
- 6stack and hp-hdx). The headphone is currently working, but no other
- speaker.
+ *** WORKAROUND **
+
+ * If model is set to 5stack-no-fp and "Line Jack Mode" = "Line Out" then
sound works (Some channels have to be unmuted)
+ * After each reboot the "Line Jack Mode" must be set to a different value and
then back to "Line Out" to make sound work

This bug could be related to 400682, but it is a slightly different
notebook and sound card.
