First, I've used Skype, Ventrilo and Mumble and everyone can hear me clear as day. Whenever I use TS3 people say that my voice is really muffled. If I switch to Vent or Mumble, they say my voice reverts to normal.

I am using Corsair Vengeance 2000 headset and the issue persists whether I am directly connected via USB or in Wireless mode.

Both my playback and capture are set to Direct Sound / Corsair Vengeance 2000.

I'm not sure what the issue can possibly be. Does anyone have any suggestions on settings that I should look into changing? I want to also mention that when I do a mic test, I sound clear as day with no background noises interfering.
