Server Version#:1.19.2.2737(smb)
Player Version#:8.0.0.17276
I’m using 2019 Nvidia Shield TV Pro as the server, and MiBox S as the player in the same network.
I have about 10 MKV videos with lossless Dolby Atmos (shown in Plex as TrueHD 7.1). Whether Passthrough enabled or disabled, if I try to play any of these videos, Plex just shows the waiting circle forever without any error message.
If I switch to a different audio track of the same video, for example AC3 5.1, the problem disappears.
I tried the same videos on Plex web & Plex for Android phone, and there was no problem.
I don’t think my old Mi8 phone can do Dolby Atmos, but even the Android mobile version Plex can play those videos properly. So I don’t think the problem is with the server.
I Googled “Mi Box S TrueHD” and found many reports that the box does not passthrough TrueHD or dts-HD audio. I did not see any reports of successful passthrough. This was for both Kodi and Plex.
AFAIK, the Shield is the only Plex client that will passthrough TrueHD.
