This was a problem in CS6 and was fixed in the first version of CC. Now that Premiere Pro has had an update, the right click link to "Edit in Adobe Audition" is broken. In CS6, it didn't even show as an active link. In CC it shows as active, and when clicked on, saves the audio track as "soundtrackname Audio_Extracted" then does nothing. I can't go back and forth when trying to fix the sound. Perhaps this is a bug that Adobe re-introduced in the program?
