lately (this past 3 months about) my push to talk has stopped working randomly. and it is completely random. what happens is the first and main thing is it decides to stop working. i hit my push to talk which is left control and it doesnt work. the little light next to my name doesnt light up at all. another thing is when i go to try to change the button to another button i hit the button i want and it doesnt register. so if you need anymore info to help me fix this ill gladly tell you.
