Sorry if this is a question that's too specific. I have a Raspberry that I bough for one project and now it's surplus to requirements, so I might try and build it as a media player.
A problem I have is that my 10yr old AV receiver only has an optical input, so it can handle DTS and Dolby Digital, but not Dolby Digital Plus.
I've just returned a Nvidia Shield, which I believe is based on Kodi, because Netflix and Prime have been built to not support any 5.1 standard earlier than Dolby Digital Plus. I know the rig is set up right because Plex from the Nvidia Shield gives DTS 5.1 in full.
But, netflix and prime come through in PCM 2.0.
Before I start a long path of learning, does anyone know of a platform I can use on the Pi where netflix + prime apps have licenced Dolby Digital?
Edit: I should mention that I have a hardware HDMI switch that can extract optical audio.
