My music audio is worse after the audio patch changes...

Everytime I play, the music has static to the point where I have to mute it, not sure what could be causing it 
I should also mention, it isn't always, but rather it seems to only happen when combat starts.

I'm using RealTek onboard audio. ALC 1150 Codec.
Submitted a ticket so hopefully it'll get sorted soon.
If not all sound is bad, can anyone locate which files are wrong? Is it a specific filetype, channel count (mono/stereo), encoding?
