I believe changes in plex media server 1.5.4 released today should overcome the issue

I just installed 1.5.4.3596 and can verify that this does not fix the issue for Docker users (at least not for me.) I can play the video with version 1.4.4.3495 though so I am reverting back for now.

Updating my docker container to 1.5.4.3596 worked for me on my FreeNAS server.

That is different issue and does not relate to the transcoder temporary directory. Could you raise separate forum topic for it please with logs and environment setup details.
1.5.4 appears to solve my transcoding problem when running in an LX SmartOS zone.
Still getting this error after updating to 1.5.4.3596

Just an FYI it appears the Plex teamâs fix for this issue is breaking the audio conversion off to its own temp directory in /tmp, not the most ideal fix as there is no way to configure this. The new way also completely ignores the temporary directory settings in the Plex Server settings.

Yes - this is what is used now. The /tmp system directory for the audio transcodes

Iâm not getting anything in /tmp/ when itâs attempting to transcode audio.
Coming in late to this discussionâŚI see a few interwoven things here and ask for clarification.
Is this best sumarized as a file i/o time-out when attempting to read from the /tmp directory within a docker container?
If so, where is the docker container with respect to the host (on a network) and has /tmp (within the Docker container) been moved to a location outside the container?
If any of the above questions are true, please expound as where they resolve to.
If Iâm still missing the file i/o issue, please help me understand.
Additionally: May I have a full set of log files? Settings - Server - Help - Download Logs? (attach the ZIP file here with a post)

Birth: -Iâm not getting anything in /tmp/ when itâs attempting to transcode audio.
I set everything in /Codecs/ to 777 and that seems to have resolved my issue for now.
Iâm running PMS on Windows 7 and since the 1.5.4 update today, Iâm not having trouble with True HD audio transcodes from NAS content that started today. I can direct play them from PMP on my Plex Server but not on any client that requires audio transcode.

It doesnât work for me with 1.5.4 on a synology nas either.I removed the specific setting for the transcoder folder. As a result the data is written in /tmp/pms-585a8427-0bc7-4062-acc7-eb70e4a06604/EasyAudioEncoder with 755 permission mask with files inside the âConvert toâ folders with a 644 permission mask. The /tmp folder is located in the general aufs overlay of the container. Up to 1.5.3 it was located in a subfolders of Library if no specific transcoder folder was specified.
mounts inside the container:
... none on / type aufs (rw,relatime,si=8afe44667b095b1c,dio,dirperm1) /dev/vg1001/lv on /transcode type ext4 (rw,relatime,journal_checksum,synoacl,data=writeback,jqfmt=vfsv0,usrjquota=aquota.user,grpjquota=aquota.group) ...When the transcoder path is changed to /transcode and a volume is mapped to /transcode the result remains the same.
Appearently the docker inspect output is not enough:
{ ... { "Source": "/opt/docker/plex/transcode", "Destination": "/transcode", "Mode": "rw", "RW": true, "Propagation": "rprivate" }, ... }Since synoacl is specific to synology, i am pretty sure that docker controlls the mount parameters, doesnât itâŚ
Sorry pasting the oringal response of sa2000 didnât worked well, so i did split the quote into two blocks.

I posted this originaly in https://forums.plex.tv/discussion/267052/transcoder-fails-with-docker-version-1-5-3.
As there is no ERROR - Unzip: could not set executable bit on output file in logs, i moved the post over here.
The details of the mount command are provided in the first code block and a log snippet is attached. The /tmp folder uses the first set of mount parameters, while the /transcoder folder uses the second set of parameters.
The file I tried to transcode with 1.5.4 can be transcoded with 1.4.4.3495-edef59192 without an issue.

Please raise any issues you still have with transcoding on the windows Plex Media Server forum providing server logs and indication of time of the problem and what device and what plex client app

Thanks for moving your post to this thread. It is only audio transcoding that now uses the /tmp directory. The setting for /transcode directory would still be needed for other transcodes
The issue that you are getting is that after the transcode job is started, e.g.

Could you get directory listing showing directories/files/date/time/sizes/permissions

You will need to complete the path
I attached the output of âls -ailRâ output the post and added the matching log snippet.
There is an odditiy, though. In the tmp folder everything except the filename extention is correct. Plex expects *.wav, while the files in the tmp folder have the extension *.ec3.

Can you see an EasyAudioEncoder process running?
There is no EasyAudioEncode process running, just â/usr/lib/plexmediaserver/Plex Transcoderâ.
See attached output of `ps -auxf´ (best to be viewed with an editor which respects unix line endings).
Further testing:
I executed /config/Library/Application Support/Plex Media Server/Codecs/EasyAudioEncoder-133-linux-ubuntu-x86_64/EasyAudioEncoder/EasyAudioEncoder from shell and got following output:
âDolby, Dolby Digital, Dolby Digital Plus, Dolby TrueHD and the double D symbol are trademarks of Dolby Laboratories.â
docker log ${containerId} prints out a couple of those lines as well. So appearently it is at least calledâŚ
If i start EasyAudioEncode as a background process from shell, i can see it in top. Though, If top is running in the shell and transcoding playback is started from a client, it does not appear in the process list.
Thanks @kopfpilot - need to get you a linux person
@sa2000: thank you 
Btw. the transcoding itself seem to happen in the background: the cpu load rises and the temporary EasyAudioEncode file keeps beeing replaced iterativly with a growing index number (caee72199bcdf59e-com-plexapp-android_834-1-n.ec3, where n is the index number), until playback is stopped.
