Ok so i am having some issues with AudioDG.exe making it imposible to play my games in windows vista with sound. If i kill the process the game runs smoothly just no sound. If AudioDG.exe is open it just starts taking like 100% CPU when i start the game. But here is the weird thing , yesterday i reflashed my bios and then i tried running halo 2 pc. The game started fine with sound and i played for like an hour no problem. I tought my problem was fixed .......... Of course after i closed the game everything was back to the typical not working windows vista. I tried reflashing the bios again didndt do anything. Anyone got any ideas ?

Also ive already tried disabling the enhacements for speakers /headphones and Digital Output Device doesnt help.
