Lost AC3 Audio on Fire TV…
Just verified both aac and ac3 work on my fire stick. Is this happening for every movie you play? Maybe reboot the fire tv by holding down the Select button and the Play button until it reboots. If it still happens, verify what’s happening on your dashboard as it plays.
Have tried rebooting everything that is humanly possible. Fire TV
will not play ANY AC3 audio file (with video). My ROKU’s are
working just fine. I have had nothing but issues with both Fire TV
cube and PLEX.
