I'm getting an error: Cannot Open Wave Out Device or Audio Device is in Use.

I"m getting an error: "cannot open wave out device" or "audio device is in use."

Go into the Windows Control Panel and open up "Sounds and Audio Devices." Click on the Audio tab and make sure that the default playback device is correct. You should select the driver for your soundcard in this setting.

The problem is often caused by some other program or sound driver installing its own default playback device.
