I recently purchased the MEKA headset from Razer. I went to try it out on my computer, and it worked just fine, the noise was clear and it was comfortable. Then I realised that my computer wasn't picking up the microphone (the headset does have one, it states on the box that it has a multipurpose 3.5mm jack). Whenever I plug it in the output outlet, noise only comes out and the mic doesn't work. When I plug it in the input outlet, the mic works perfectly fine but I can't hear anything. Am I doing something wrong, or is there a way I can fix this issue?
