I've been using a USB headset for quite sometime for gaming, and about in March my mic stopped working. The sound works fine, but the mic won't work. I figured initially my mic was fried. I went out and purchased a new mic, and I'm still having the same problems.
When I go into my volume controls, my mic is turned all the way up, the mic boost is on, and the proper device is selected in voice and what not in the advanced controls. My mic is not muted.
When I go into sound recorder, I can blow into my mic and hear the static, as well as dimly hear myself say 'hello'. Another reminder, mic boost is on.
I've updated all my USB ports, restarted using different ports, etc. NOTHING.
The only thing I can find is in my device manager, my multimedia device manager has the yellow !, i've tried rolling back, updating and disabling this thing and that won't work...
I'm self taught in most of these things, the only other suggestion i haven't tried is updating BIOS or w/e and I don't know how to do that.
