My situation is the same as above:
Plex:
DTS 7.1 is received as stereo PCM by soundsystem.
DTS 5.1 is converted to EAC3 5.1 and received as such by soundsystem.
Kodi
DTS 7.1 is received as DTS by soundsystem.
DTS 5.1 is received as DTS by soundsystem.
Setup:
Philips TV with ARC connected to Philips Soundbar B97/10.
If Kodi can handle it, so should plex.
