Mic lag. Especially in TTT but also in other games.

So I started playing Gmod again and after joining a few servers, and alot more TTT servers, I noticed my mic would lag every time I pressed ‘x’ , which is the key binded for voice chat by default for me. Every time I press it my screen freezes for 4-8 seconds, and this can be quite frustrating while I am trying to call out a traitor or who I am with. This has never happened to me before, and my computer has always ran gmod smoothly in the past. Plus, I have little to absolutely no lag when pressing the voice chat key in CS:S or DOD:S. Here is the link to the type of mic I have right now, which has served me well in the past. http://www.amazon.com/Logitech-ClearChat-Comfort-Headset-Black/dp/B000UXZQ42/ref=sr_1_16?ie=UTF8&qid=1339529087&sr=8-16&keywords=logitech+mic

This also happens to me. I have no idea why.
