Hello BIGGD,
Have you configured the mic in the control panel ?.
Go to control panel and open Sound, there you will see a panel that looks like this, highlight the mic you are using and configure.
Also if you are using the mic in a game, you may need to configure the mic in the game sound options, make sure you dont need to press a key to transmit.
Hope some of this helps, Good luck and post your results.
