Windows 7: How to stop other stereo mix looping other people on teamspeak

Hello,
Im running Teamspeak 3 and I use stereo mix to stream sound to my friends, the only problem is that whenever they talk Stereo mix plays their voice back and causes insane feedback. I would just mute everyone but that would mean I cant hear them myself.



Is there any way to change it so that stereo mix wont pick up their voices let me still hear them?
(I have 2 recording devices, Microphone and StereoMix. I have 2 playback devices, my HDMI to the TV and a Speaker output.) I use VIA High Definition Audio as my drivers.

First, you should check if your sound driver supports background noise cancellation, that should help a bit.

Secondly, take a look at Team Speak settings and make sure your only input there is the microphone channel and not stereo mix.
