Hello there, since the title sounds (and this is not an euphemism!) weird, here I post a screenshot:



As you can see on the left and right side of the screen I can actually see the audio that is playing currently in game! (This glitch gets worse when there are more sounds)

Removing my headset or turning all the volume to 0 has removed this strange glitch, but.. I'm not able to hear any sound or music in game obviously!

This is my computer and specs:
Toshiba Qosmio x770 (Laptop)
- Cpu: Intel Core i7-2670QM 2.20Ghz
- Ram: 8GB DDR3
- GPU: Nvidia Geforce GTX 560M

My Headset is:
SteelSeries Diablo 3 Headset

I've updated my laptop to Windows 8.1 and all the drivers and programs (relative to my headset and hardware in general) are updated too.

Can anyone help me?

Thank you in advance!
