Sorry my bad again it was working perfectly, just missed a step.

I'll add the dumps as an attatchment. I had both external headset and
microphone plugged in and let the VM run in the background for ~30min while
doing other stuff. I did not play music or test my microphone in the VM
either, If i did anything wrong, please tell me!

It stopped at 0x104f4
