No 5.1 Sound AC3 or DTS

The same file that will play via iTunes Movies in 5.1 surround will only play in stereo through the Media player (my amp automatically switches into PCM stereo mode when file is played via Media). It is an m4v file. I am doing another convert of the same file to mkv to see if that will make any difference.

The original DVD file still on my computer also plays in 5.1 when I select it through Media (My files - computer). So Media will play 5.1 but it seems not from the m4v file.

Also it will not see any Music files stored on a NAS which play fine in Plex (but not xbmc). Just get “there are no items for playback” message from Media

 

The mkv file doesn’t play 5.1 either
