M2TS files with a TrueHD track are not shown in DLNA clients libraries

[Former user]

Serviio is not publishing M2TS files with a TrueHD audio track to DLNA clients (Generic Profile). They are however added to the Serviio server library and can be seen in the Serviio MediaBrower. Only the publishing to DLNA clients is affected.

The problem does not exist when the same file is remuxed into a MKV container.
