In CC4 ( 4.02.0718.1):
-open the Talking Kevin sample project
-Render --> Render Video
-Click on WAV (Format drop down menu)
-Click Export and save to file
-nothing happens, no wav file is being created

In IClone, WAV audio export works fine with Render --> Export Audio

Suggested solution: fix audio export in CC4 or remove the WAV option
