I just found out how Dolby Digital in Live TV still (or again?) works:
set your audio configuration to 2.0 channels, activate passthrough and(!) "enable Dolby Digital (AC3) transcoding"
Now both, video files and Live TV 5.1 is working fine with my Fire TV (v1).
I checked with an ac3 test file and Live TV (Star Wars, e.g. the spaceships were clearly hearable coming from the back, flying to the front)
