Using on board audio? have you updated driver and done a fw update on mother board?

If not internal again try driver update or putting in a different pci slot

That you've not mentioned a dedicated sound card I assume you are using the onboard sound?

Onboard sound is notorious for conflicts, try a descrete card such as: (from most expensive)

• Asus Xonar HDAV1.3 - with this you'd loop the HDMI lead from your GFx card to the Xonar and then to your TV/HDMI amp.
• Asus Xonar D2X - has optical and coax S/PDIF out.
• Asus Xonar D1 - has a S/PDIF header on the card to connect to your graphics card.
