Yamaha R-N402 DLNA m4a issue



Hi all,
I am trying to playback music from a Plex Media Server Version on Debian on a Yamaha R-N402 MusicCast HiFi integrated amplifier through DLNA.

With standard config, the R-N402 is mapped to a generic profile, where flac and mp3 files play well. However, m4a files randomly stop playing and some files were not recognized at all.
The same happens using the Musiccast profile that circulates in this forum (see attached adapted profile from NX-N500-Speakers).

Any insight is highly appreciated.


Also, ogg files do not work at all
