Microphone Problem

[icekidjh]

I have a microphone problem.
When I play this game that allows voice-communication, it says: Unable to intialize DirectSoundCapture. Trying waveIn.MMSYSTEM004. The specified device is already in use. Wait until it is free, and then try again.

but when I tried it with Audio Tuning Wizard, Voice Tweak, other recording programs, it works fine.
I'm not sure how to fix this.
Please help.

And some information about my problem:
My cpu: Pentium 3, 800Mhz, my video card: 113 MBs
It works with other games...I think its some program using it, but not sure how to fix it. Would anybody help?
