Does Roku 3 support pass through and playback of 5.1 surround flac files? When the audio stream arrives at my receiver it is always 2.0 channel PCM transcoded to 48khz. I've tried 5.1 flac files for DTS and Dolby Digital.
My Roku settings are set for surround and streaming content works for other channels such as Amazon Prime and Netflix.
I'm streaming the flac files from my NAS UPnP server.
