Sound issues... Again

A while ago i posted asking for help with my sound heres the story....

I bought prophecies about 5 months ago and one month later when i was playing the sound suddenly stopped, but.... all other sound from other games and my media player and everything work fine.

Last time i posted this i got several responses but had no luck fixing the problem so i decided to play on without listening to music but now i'm getting sick of not being able to hear my GW music so i'm going to attempt fixing it again.

Things to keep in mind:
I tried...
Re-installing GW
Buying new sound card
Playing around with every possible sound option on my computer



So if anyone can think of something i havn't tried or anything like that which can possibly help me it would be greatly appreciated =D

My sound cuts out somtimes but comes back when I restart GW... :l
