It's a very common problem. All you will have to do:
  • 1.Go to Start then Control Panel
  • 2.Double click on the Sound Tool
  • 3.Click on the Recording tab
  • 4.Right click and select "View Disabled Devices"
  • 5.Enable the Stereo Mix


Good luck

If you are having a problem finding 'Stereo Mix' in your recording tab, you should search the web (primarily Realtek website) for latest Realtek AC'97 or HD Audio drivers. Once I downloaded that and restarted, Stereo Mix popped up and I enabled it. I fought with the iw3mp.exe crash for a while and this finally worked. Hope it works for you, good luck!

Hi All!

It is also a solution, if you do not see Stereo Mix, to plug a microphone to your computer. It has been worked for me.

Plug in your Sound AND a Microphone together at the front or back of your computer.

Now start the multiplayer.exe

I just tried it and it worked. First time I've been able to play the multiplayer...
