Can't play M4A music using Firefox - works in Safari

MacOS 10.14.6, Emby 4.3. I am trying to play my Apple Lossless encoded music from an Emby Server on Windows Server 2016 using Firefox on Mac. None of the files play, giving the error "No Compatible Streams Found". The files play fine using Safari, but it's kind of annoying having to use a different browser just for this one app. Firefox also plays the files fine using its own built-in media player if I connect to the server via FTP and click on the files, so I know Firefox supports the file format. I was using Plex before in Firefox, and it had no problem playing the files either.

 

How do I fix this problem?

I am having the same issue with m4a files on both my TOS based server and my Mac OSX server - Firefox on MAC will not play the m4a audio tracks. Safari on Mac OSX and IOS app and Firefox all play m4a fine. mp3 files play fine everywhere.

 

This is apparently a Firefox on MAC issue - Firefox 76.0.1 (64-bit) and macOS 10.13.6 any ideas?

 

Thanks,

I am not sure where to find it.  Apple MPEG-4 audio is what is listed when I get info on the audio file.
