Windows 7 Doesn't Show Microphone

I bought these new headphones Ozone Attack, and the sound works great on them, but the microphone doesn't work in any program. Doesn't work in Skype, TS3, and it doesn't even pick it up in Recording Devices. It's the kind of headset where it's not a USB; it's got a plug for the mic and another for the headphones. They're both plugged in firmly, and I've updated my audio thing which is IDT High Definition Audio CODEC. My laptop is a HP Pavilion g6-1241sa Notebook PC. I've also gone into Recording Devices and checked for any disabled mics, but the one in my headset isn't there. And even though my headset is set as the Default Communication Device, the mic doesn't get picked up under Recording Devices. Push to Talk is also not on. The headset is also shown only under Playback Devices.
