The fix is probably the same one Luis posted recently for someone else's 
audio problem. Do this:

1.open Audio MIDI setup (Applications/Utilities/Audio MIDI Setup.app) 
and check the Audio settings.
2. Change the Audio Output setting to 44100.0Hz
3. Quit Audio MIDI Setup.

Some applications reset the sound level to a very high Hz that many 
other apps can't handle.  Those applications that can use these 
unnaturally high levels continue to work, but others don't.

Whether or not you use MIDI doesn't matter. The Audio MIDI Setup app is 
just a way to control the system audio settings. Every time I use 
Audacity I have to reset the audio levels again before Rev will play sounds.
