Thanks for the info! It looks like your chipset 82801H is supported by 
snd_hda in 7.1, and I have it in our list of supported sound cards. Can 
you test it out on PC-BSD 7.1 a bit later this week? It should just work 
out of box. If not, send me the diagnostic sheet again without reverting 
to the other OSS driver.
