Cant transmit

[Ltbilldo]

On TS2 i cant transmit sound, but i can recieve it just fine. I use sound recorder and it transmits so it cant be my microphone. Im not very computer savvy so after the sound recorder test i dont know what to do, if i had some help here on some tests or something to run it would be very helpful.

My sound carder is Creative Sound Blaster Audio PCI 128d
and im running Windows XP

Thanks for help.
