How to force transcoding to AC3 or DTS at HTPC

I’m not sure where the user profiles folder on my QNAP NAS should be. Does anyone know?

Plexopedia says:

The path of the Plex user client profiles are located in the following path:
[Plex Application Data Folder]/Profiles
Note that the Profiles folder will not exist by default. You will need to manually create it and add the profiles to the folder.

A Plex employee in this forum wrote an article about DLNA profiles in this forum explaining:

User profiles are authored by individual users and are never changed by the server. User profile files are located in the Plex Media Server user directory, in a directory called Profiles. If you have never authored a user profile before, this directory will not exist.

So, the first source mentions the Plex Application Data Folder, the second source uses the term Plex Media Server user directory.

This article from Plex support explains the location of the media server data directory on my QNAP devices to be

/share/ZFS530_DATA/.qpkg/PlexMediaServer/Library/Plex Media Server

which indeed exists.

So I’m gonna create a folder called Profiles here and put my changed profile file “Plex Desktop.xml” inside. I found the original file here:

/share/ZFS530_DATA/.qpkg/PlexMediaServer/Resources/Profiles/Plex Desktop.xml
