Be Right Back, Uninstalling

So, recently I went through a whole left 4 dead versus match normally, calling out boomers etc. when one of my teammates asked me why I wouldn't talk.

Apparently my mic's been broken for about a week and no one told me.

So!

I've been trying to figure out what's the problem. I have a headset, and the speakers work fine. I tried taking the dual cable setup out of the usb adapter and using the two jacks separately. Didn't work. I tried moving the usb adapter to different ports. Didn't work. I started fiddling and faddling with settings. Nothing.

Any ideas, or should I spring for a new set of headphones?

Headsets break on a regular basis, mainly do to the constant flex in the cord and increased crushing by chair wheels.

Buy a new one, or a new desk mic as they last longer.
Stay away from USB.

Yea definitely buy on with dual jacks, the quality difference is huge.
