ANYONE ELSE GET AN INITIALIZATION PROBLEM WHEN I START UP COD2 IT SAYS THAT I JUST INSTALLED A NEW X800 GTO WITH THE 6.1 CATALYST DRIVER

------- sound system initialization -------
Attempting 22 kHz 16 bit stereo sound
couldn't initialize 2D provider: waveOutOpen() failed.

I used the moega driver first and it said the same then i uninstalled it and tried the catalyst and also same thing and now my sound doesnt work
