I have the transcoder temp folder on ‘Plex Media Server’ set to a custom location (‘D:\Plex Media Server’), if this is what you are referring to? I don’t see a setting for transcoder folder in ‘Plex for Windows’ (am I missing something?).
EDIT 17-Feb-2021
A solution has been found. Thank you to Plex user erkston, who emailed me. The fix is to manually install the Dolby decoder file to windows. This solution is taken from an Adobe support forum thread. To perform the fix, follow the instructions below:
- Download the codec DolbyDecMFT.dll.
- Copy it to
C:\Windows\System32\and toC:\Windows\SysWOW64\. - Register the codec by running the following commands in an Administrator CMD window:
regsvr32 c:\windows\system32\DolbyDecMFT.dll
regsvr32 c:\windows\syswow64\DolbyDecMFT.dll - Reboot the PC and EAC3 audio will play from ‘Plex for Windows’.
