I have a Sennheiser PC330 headset, which is just a normal aux headset for microphone and speakers. The speakers are working fine, but when I plug in the microphone VIA recognises it as the front mic when plugging in, but nothing else recognises it. When I try to use it in Windows 8 to set up microphone it can't detect it or anything and was wondering what the issue is or a possible fix? It's not under hidden devices or anything like that, it just cannot find a microphone.
