I’ve noticed if I have Direct Play set to Forced and Passthrough set to Auto, that there is no mention of transcoding of audio occuring for TrueHD or DTS HDMA.
My soundbar supports these formats but unfortunately doesn’t display the type of audio stream being received.
Is the audio actually being transcoded to LPCM, decoded to LPCM at the Shield as a client? I’d love to hear it’s been passed through but I don’t think that can occur without specific support?
Does anyone have a receiver or TV which displays the type of audio stream being received under these conditions?
Edit: Alternatively, someone who has a receiver that doesn’t support TrueHD or DTS HDMA could try these same conditions to see if they get audio.
Edit2: I’ve tested again and with the newest PMS, DTS HDMA is working so I’ve updated this post accordingly
I leave Direct Play on Auto, there’s really no need to set it to forced. DTS-HD MA will direct play. TrueHD is not yet supported. What model soundbar do you have? I doubt it actually is able to support TrueHD at all. Until Plex support TrueHD, which is not yet, it will transcode to 640kbps AAC. DTS-HD MA should direct play with no issue. This is assuming your whole set up is HDMI and optical is not involved at all.
Turn on the display that shows you if stuff is transcoding or not. There is an option in the SHIELD settings.
Plex doesn’t attempt to direct play DTS-HDMA unless I set it to forced. My sound bar is a Yamaha YSP-2500 so it supports it.
As mentioned the display says it’s direct play and the Plex server logs corroborate the display. The question is what is what the Shield is outputting?

What does your receiver read when you force direct play with TrueHD? Does any audio actually come out?
Yes, I get audio which is why I thought it interesting.
I went through the menus of my sound bar and found how to display the audio stream so I can answer the question.
Direct Play forced on a TrueHD file doesn’t transcode at PMS and outputs DD 5.1 at the Shield. I’m not quite sure how, but that’s a different question.
Regardless, I wouldn’t get to hung up on TrueHD for now. TrueHD transcoded sounds like ■■■■ anyway. I have just been keeping the DD track for TrueHD movies and using that until TrueHD passthrough is fixed.

Sorry, I hadn’t seen this thread. I would guess that the video player is automatically detecting the unsupported audio track and falling back to the “next” audio track in the file. Does the video you’re playing have multiple audio streams?
