The RPi is well worth it as a media player running kodi. Compared to my TVs built in player and RPi the sharpness and detail difference is day and night. No lag when running through the menus. Regarding streaming hd audio, I get pcm in my receiver then probably I'm having hd audio din. Cool! You just won't get hd audio (dts hdma, dolby truehd) appearing in the receiver.
