Alright, I got absolutely no solution for this whatsoever, looked everywhere. None Works.
Motherboard: M4A785TD-V EVO
Headset: Koss SB/45
Problem:
No sound at all. So basically I've looked everywhere, checked for bulging capacitors (none) to removing and installing drivers and shit.
Some pictures to help you understand:


No speakers are muted. I am 100% sure of that.
If you got any ideas how to fix this, let me know.
Any answer is better than no answer. Thanks.
