Mic/Sounds problem

[Amailer]

Hello,
I got a slight problem with my mic and what users who I speak to over the internet hear. See, when I use teamspeak what ever I hear on my computer (msn sounds, music, errors) they hear, so if im on teamspeak, and I speak while someone else is speaking and echo takes place (cus they where them selfs speaking -- cus of the problem with my comp or w/e) you get it?

Anyone know how to fix this problem?
These are the settings I got in my volum controle

Play Controle
Wave
MIDI Synth
Auxiliary 2
Line-In 2/Mic 2
S/PDIF-In
CD Digital
Auxiliary
CD Audio
Line-In
PC Speaker
TAD-In
Micrphone


Thanks.

use a headset. This way your mic/speakers are separate so you don't get feedback

I am, but still it happnes. How to make it so that I can't hear my own voice?

Try this.
In volume control, go to Options > Properties. In Playback make sure Mic is checked. Then, make sure it's muted. This should work, I think.

yup, it is check and it is muted. But no diffrence.
There is a.. Line-In 2/Mic 2 but if i mute that, the mic doesn't work
