Under my setup pre Sonos this all worked fine, but since the Playbar, I get video on the movies, but no Audio.
Any help is appreciated.

What's playing the movies? Is it an app on the AppleTV, or are you streaming video in some form from the Mac Mini using an application to play the movie there, and have the video show up on the AppleTV?
I suspect the ultimate answer that is causing the issue is that the sound that's being streamed in whatever manner isn't a Dolby Digital or Stereo stream, but instead some other audio codec. Which means that the Sonos wouldn't be able to interpret it. Take a look at whatever "player" device is operational, and make sure that the sound settings are set to Dolby Digital. On the AppleTV, it may not be in the app itself, but in the AppleTV's audio settings.
While you're poking around in audio settings, it might be worth looking at the Samsung's audio settings, and make that be Dolby Digital as well.
