Not playing video if BT is connected

Server Version#: PlexMediaServer-1.40.4.8679-424562606-x86_64
Player Version#: com.plexapp.android 10.18.0.968

plex on android-tv (Nvidia shield) does not load video and times out with an error only if Bluetooth headphones are connected.

from the logs, it tries to transcode EAC3 audio and fails. logs are attached

My Plex client audio passthrough settings are set to HDMI. the video fails to play if I change or disable passthrough settings even without Bluetooth headphones. so the only way it plays is if I set the audio passthrough to HDMI.

I do not experience issues with any other audio format.

older reference with the same issue
Plex player fails to play EAC3 5.1 when BT headphones are connected - my previous topic
Reddit - The heart of the internet - community topic with some suggested fixes that do not work for me
Amazon Digital and Device Forums - US - a fire stick device that has a similar issue, might not be one to one but has to do with audio transcoding starting up.

Do you have any subtitles enabled when you start playback?

by default, I have a setting that forces English subs for all media.

I have tried disabling them for a series now and starting the media again with BT headphones connected - same error message.

Ok and if you disconnect the BT headphones start playback normally then change the quality to force it to transcode does it play fine?

If I start media without the BT headphones connected - it starts. Then if I turn on the BT headphones - it connects and continues playing fine until the next file opens or I try to change the playback settings like subtitles. If I do that - it stops again.

I am not sure what “changing the quality to force to transcode” means.

Yes I know it starts without the BT but connecting the headphones is causing your server to transcode the audio as EAC3 is not supported over BT. So I just want to confirm if your server is failing to transcode as I am able to play over BT fine.

So what you need to do is start playback normally without the BT headphones, once playback is busy bring up the OSD menu by pressing down on the remote, then on the bottom right, click on the HD button > select Show All > then select a low quality like Convert to 320p or 240p. Then let me know if it plays fine

it does not play.

Ok seems your server is failing to transcode then. Would you be able to share your PMS logs? And what are your server specs?

the logs are here (separate link, not as an attachment) - Microsoft OneDrive

CPU is i5-6600k.

strange, I remember before the EAC3 became popular I was able to transcode video.
just tried another media with AAC 5.1 audio codec, it started up, I was able to lower the playback quality and it plays.

Thanks, I have forwarded on the logs to see if I we can see why its failing.

Dear All,
Any news regarding this issue with bluetooth headphone and EAC3 ? I have the same issue with my shield TV pro. When i play a movie or a tv show with an EAC3 sound, plex player stop playing because Plex try to convert to opus… I have this issue only on the shield pro TV. On my TV directly with bluetooth, no problem…
Tks by advance

cannot say definitely, as I have (temporarily) switched my Plex server from a Windows virtual machine to the Plex server on Nvidia Shield and the issue is resolved. Nvidia shield server transcodes with BT headphones connected (but it still falls back to transcoding, not direct play).

the likely root cause was that Windows VMs are not supported for hardware transcoding on the Plex server. I remember some KB I’ve seen, but unable to locate the link at the moment.

and there are some shenanigans when the PLEX server with hardware transcoding enabled tries that on a VM and fails not falling back to software transcoding. Just a wild guess.

The next step is to try to play around with containers to see if I can make it work.

On my side, I even try with another apps (sorry plex staff) on my shield pro : Nova media player or VLC, no problem with EAC3 and my bluetooth headphone.

So the problem came from Plex player…

Hi !
have you found a solution ?

tks

workaround - start media playback and connect the BT headphones when it’s already playing.
solution - no solution, yet.

Any updates?
