I've just downgraded my OS from x64 to x86 (WIN 7) because I didn't know what else to do to get my HD2 ADVANCE to work correctly. However this damn problem persists. Suddenly the card stops sending sound out of its audio output (either RCA or optical) and I just don't know why. Is it the drivers? I've tried the latest downloaded from this URL and also one that you sent me some time ago (V550A). I know is almost impossible but I really wish I could return this item and get a complete refund.
I NEED A SOLUTION PLEASE! Thank you.
