Android tv fails to play multi channel m4a files

Issue description:

I am unable to play some multichannel m4a files, and symphonium seems to believe that they’re mp4 instead. I did see a similar issue in the past. If needed, you may contact me to get a link/login to the jellyfin server that hosts the files. I am using the native android tv client, and connected to a 5.1 system via hdmi/arc if that is any use.
