Check the kernel message.  Don't you have a message like "hda_intel:
msi for device 1043:829c set to 0"?  Otherwise give alsa-info.sh
again.

But, essentially this is a problem of your mobo and Linux MSI
handling, not exactly a driver issue, IMO...

I guess the problem will go away if you remove your another sound card
on the PCI slot.  Or maybe it'd work even by moving to another
slot...
