Can you activate movie audio from iCab

The manual is not online yet, but I believe you can since it is activated by the towercom icon (button 2) . To get the more traditional crew chat you have to use a non standard icon, I think it's button 5

Thanks for the suggestions.  I played around with the icab app today and could not figure out a way to activate the audio.  On the plus side, I did finally write down all of the audio clips from the movie.  I like that the iCab lets you turn down the chuffing sounds while the other audio remains at the original volume setting.  Allowed me to hear the in motion audio tracks better.
