I'm using TS3 on Windows 7 with a head set and a microphone. As of the last two days the people who I am talking to have informed me that the longer I talk without stopping the more muffled I get, until I sound like I'm underwater and they can no longer understand me. It isn't my microphone, as I've tested it with other recording software and I sound fine. I also went into a ts room, recorded myself and played it back, and once again I sounded fine. It doesn't seem to matter whether I use Push to Talk, Voice activation, or continuous transmission, on all of them, according to those I'm speaking to, my voice slows down, gets quieter, more muffled and "blurred."

I have turned Echo Cancellation and Reduction off, I've turned Automatic voice gain control off, and Reduce background noise off. Does anyone have any idea what could be causing this?
