Finally got sound using pci=use_crs on the grub boot line. Don't know what the
hell this does but at least sound works and no kernel oops at boot.
so what I did:
I took a backup of /etc/default/grub to /root/etc_default_grub_backup
then
opened the file /etc/default/grub with my favorite editor vi.
I installed ubunto 11.04 (amd64) today.
Same problem, VT1708/A [Azalia HDAC] using snd-hda-intel (driver)
aplay -l
was showing no soundcards detected.
I searched through many forums and ended up on this page. /bugzilla. kernel. org/show_ bug.cgi? id=16921# c5

find the line
GRUB_ CMDLINE_ LINUX_DEFAULT= "quiet splash"
modify it like
GRUB_ CMDLINE_ LINUX_DEFAULT= "quiet splash pci=use_crs"
save the file (/etc/default/grub)
after saving the file I ran update-grub like
sudo update-grub
then I restarted my ubuntu 11.04.
yes.... perfect the sound is there!!
now if you check "aplay -l"
