A couple of day's ago my friend's started complaining that everything they said in vent, ( while I was holding down my mic) would echo back 10x louder.
Then, it just stopped working.
Sound still works out of them, and friends say that they can hear what I hear, music for instance, they can hear if I hold down my mic in vent.
If I go into the test audio thing in control panel, if I move my headset around and scream and such I can get the bars to go up.
I think I said this to someone earlier, How good are you with a solder Iron, you need to find the break but you did say it is loud with the mike in vent so at the moving part is where you will find the break.
