I was playing witcher 3 when this randomly started happening. I have a hyperx alpha with the external sound card and a steel series Siberia V2. I can only get them to output in mono, I have tried everything i possible can to fix the issue. I have reinstalled all drivers, i even reinstalled my entire OS in hopes it would go away. I thought this narrowed it down to a hardware issue, but then i tested my tv and retested the hyperx when only using the 3.5mm jack. Both of those CAN produce stereo sound. When using usb the hyperx reverts to mono. I am so confused and very angry. Help plz.
