evga 790i ultra and xhd3000

Had similar issues with my Gigabyte 790FX onboard sound (most likley Vista drivers at fault tho). I just bought a newer sound card (diamond has decent drivers for Vista 64). So first check for any updated drivers, if you still get nothing try a sound card (even a cheap one is better than onboard).

that's a possibility, but i'm hoping for a cheaper one until i get my home theater setup back out of the garage. just going to be running the speaker bar for right now and i really don't want to blow 150-200 on a nice x-fi vista card for the speaker bar.
