My motherboard, the gigabyte z370 aorus gaming wifi rev 1.0, has an integrated sound processor and bundled software that would allow me to have a 5.1 surround setup if it works. However, one of the female 3.5mm audio ports just doesnt output properly. It is the C/sub port and all sound is extremely muffled and sounds like this. i have cleaned the port out once already with compressed air and it made no difference. I have tested the speakers and they all work fine, it is just the port. I really hope that this is a problem that i can fix myself. Thank you for your time!
