Windows 7: HD sound keeping CPU usage at 100%

HD sound keeping CPU usage at 100%

Hi all this might be a hard one to solve but here is the problem...

when I plug in my speakers into the back of my computer my computer's CPU hits 100% when i have the HD sound enabled.... for the moment i am using AC'97 sound on my Asus P5KPL-CM (its on board sound).

Thats the only way I can have sound... and I can only use the front plug in port as well.

If you can solve this problem I will be ever so greatful if you need anymore info on the problem please let me know.

Cheers

P.S I had this problem when I was running Vista as well.... I don't know if its the motherboard itself or a driver problem

Normal at the front... when i plug the speakers in the back it switches to HD I think I'm not to sure... I'll try plugging in the speakers in the back and see what happens...
