I just go the latest iTunes update (as of 19th of September, 2013) and since then I haven't been able to play any of my movies, tv shows or podcasts with sound! Why is this? Please help ASAP!
MacBook, OS X Mountain Lion (10.8.2)
Same here, podcasts loose sound when put on fullscreen too.
I am having the same problem... no full screen audio when playing back a video podcast in iTunes 11.1. However, I have found I can drag/expand the playback window to almost full screen without losing the audio. If anybody has another solution, please post it. Updating to OS 10.8.5 made no difference.

OK - I had this issue with iTune movies downloaded from store, newly with iTunes 11.1, affecting all movies, even those that were once fine. The sound plays fine (Apple cinema display & sound) in large window mode but disappears on fullscreen (repeatably, coming back if fullscreen is exited).
A fix that works for me is to switch back and forth between playing on this (my) machine and another local authorised machine using Airplay - of course you can do this without interrupting playback and without exiting fullscreen using the button on the control bar. On re-selecting 'computer' after allowing the switch to complete the sound comes though fine, and this seems more-or-less stable once done*. I do not know if the other machine works, too (it is a server with no normally-on display).
FTR things that do NOT work include permnissions repair, reboot, re-alunch iTunes etc.
*PS - it works but is not stable; you can switch in and out of fullscreen without losing sound but if you switch movies (or come back to a movie previously watched) you have to go round the loop again. We need 11.2 please Apple!
My fullscreen playback doesn't play any sound
