hey guys i am having problems with VIA audio on my mobo. the problem is that the sound stops up(hangs) for a couple of seconds quite frequently. and when the VIA harware manager is installed, my PC stays at a constant 50% load. this dont happen when the manager isnt installed. also sometimes the "rear optical audio out" jack shows up in the place of the volume control!!! is my audio fxxxxd up? i got an ASUS M4A785D0-M Pro, a month old and Windows 7 x64 enterprise. i have already tried flashing bios, installing latest drivers, and my ATI HD audio is disabled in device manager.
