Microphone suddenly stops working

Hello. Im having a problem with teamspeak 3 in the last 2 days. While im gaming and talking normaly to my friends my microphone suddenly stops working but i still hear everything. I have to unplug and plug my usb headset so i can get microphone back to work. This happens like every 5-10 mins or sometimes it works for an hour. I have seen some similar reports from other users but they were talking about some Logitech Headset and it couldnt help me because im using other type of headset. My headset is Plantronics C3220. I updated teamspeak, tried older versions but the problem is still there. I just want to know if my headset is broken or something else is happening as i saw some users reported this kind of problem. Thank you :slight_smile:
