Plex Setting "Enable Dolby Digital on Apple TV" MISSING!

Hey,

 

I just got PLEX working on a Apple TV 3 (7.0.2, without jailbreak) but I was wondering why there is no 5.1 Sound.

The Solution would be to enable the "Enable Dolby Digital on Apple TV" function in PLEX, but this Setting is not available.

My question is if it isn't available for everyone since a PLEX update or is it just me?

Additionally the Apple TV isn't listed in the "Devices"-Section, although it is using PLEX right now.

Any solutions?

 

Thank You (and sorry for my bad English) ;)

Are you using a old version of Plex Media Center?

Thank You so much!
Problem solved!
