I'm really not having a good day. I think the onboard soundcard on my motherboard is faulty. It was working fine this morning. Now all I get is a constant hissing noise. Like the static sorta noise you get when you de-tune your TV.
I've reinstalled the drivers, makes no difference at all. I've tried newer drivers, still the issue remains.
Mother board is an Asus M2N SLI and running Windows 7 64 bit retail, it even does it with Windows own driver
