I play many other games and videos and music with this setup and divine divinity is the only one having problems. Its useless but I checked dxdiag and everything is okay. My motherboard is laterev with matured drivers. I dont bother trying to use the mainboard sound because its way too much hassle and im sure it wont work anyway.
Luckily the static is currently quite rare so i have become custom to it. It doesnt really bother at all anymore. Just now I played 3 hours and it happened only twice in that time.
