Hi nhumber, in my case passing it through tv will require some rewiring which I am not considering an option. I have tried the keep alive to all possible settings without luck. My AV receiver supports all audio formats and it is able to play everything being passed from fire tv. The only problem is that once DTS audio is played, nothing else plays after that. I have created a thread in xbmc forum and there seem to be other users with this same problem. None who have it resolved. I created a ticket with xbmc and logged it as a bug.
