snd_hda_intel have some bugs in old kernels.

 

the best solution is find the patch who fix your problem and apply in your kernel.

Subject: [Xen-users] cant get sound to work in xen 3.0.4

I am running xen 3.0.4 on ubuntu 6.xxx
So the xenolinux kernel is a patched ver of 2.6.16.33 and my native ubuntu patched kernel is 2.6.17
When i boot into  the native ubuntu kernel i can get sound to work, but when i boot into xen the sound stops working
however all the modules seem to have been installed properly and the software appears to be playing sound.. just that it doesnt seem to be appearing at the speakers. I have my volume at max
