Asus A7N8X Deluxe sound issues

[Tanked]

I'm using the built in SoundStorm system, and certain games (So far just Diablo 2 and Raven Shield) occasionally cause a horrible rasping sound. It's very obvious and obviously not right. I tried disabling EAX and 3D Audio in Raven Shield and the problem did not go away.
Help!

Southbridge is probably overheating causing the sound to come out distorted...get some airflow over it (that is REALLY hot and no heatsink) or get some thermal adhesive and apply a heatsink which should help it out. Luckily I experience this only on really really hot days (and stopping the music for about 5 minutes does the job) One of these days i'll apply a southbridge...

Of course, also check to make sure you're using the latest driver set...
