I have : tried plugging it into both the microphone jack in my speakers and the microphone jack in the back of my PC. Tried every possible option in the Control Panel for 'Sound Recording' and essentially fiddled with every setting that had a microphone icon near it. Restarted. Made sure no part of the system volume is muted or down very low.
I am at a loss. Any clues before I go and spend money?
Edit : fixed, somehow. Thank you. <3
