TS3 Bugs my CS

Hi, i downloaded TS3 and i've been using it for 2 months or something. last week, i aspired my computer from inside, and i also cleaned my firefox historic.
My Ts3 started bugging my Counter-strike after i do this, but i don't know if this is the fault.
Now, when i have the TS3 opened, the stereo sound just stop working, and i hear the sound from the left,right,behind...whatever as i have not this in stereo.
this have already happened to me with TS2, and i switched the microphone in TS options, and then it worked. I did it now, but still doesn't work
WHAT THE HACK?! please, help me. this is riduculous...

sorry, bad english :)

yeah, still doesn't work
