Hey guys.. new here but i got a question. I've got a basic surround sound setup, just a samsung ht-q45.. its 5.1 surround and i have it hooked up to my computer and my xbox360 with an optical cable. Now my issue is, occasionally i had a loud constant static noise when i was hooked up to my computer, but when i unplug the cable from my computer and hook it to my 360, no problems. static would go away as soon as i unhooked the cable from the computer. So I thought it was my onboard sound from my motherboard. Ended up having to get a new motherboard, but this one's got no optical, so i purchased a turtle beach sound card with an optical out. Hooked it up, installed drivers, updated.. and i've been good for awhile... But now all of a sudden today, i turn my reciever on, went to play a game, and as soon as the game started its intro movie thing, with music, i got that loud static and you cant hear anything else but it.. Does anyone have any clue as to what this could be?
