Microphone not enabled

[8mm]

Hello,

I like to use Teamspeak, so I downloaded it on my new computer that has Vista. I can hear fine but cannot transmit, they cannot hear me. Control Panel seems to indicate that I do not have a microphone but the headset is clearly plugged in. Help!

Have you tried a different set of head phones, or tried those head phones in another computer? In control panel- sounds, are all the settings enabled and set to the right device?
