This includes, among others, Transfomers 4, Teenage Mutant Ninja Turtles (2014), the one that I personally care about: Roger Waters The Wall (2015). The current TrueHD bitstreaming and decoding cannot handle these extra extensions, and will have no sound on the TrueHD track. I have found the appropriate patches that were put into FFmpeg to support this, and I have tested with my systems. Both bitstreaming to a TrueHD receiver, and SW decoding of the TrueHD seem to work. I have NOT tested with an Atmos capable receiver, but a Kodi thread seems to indicate that it should work [''once you ignore the trolls''] This problem should not be experienced in master, as the lastest FFmpeg resync should have caught this. I have not tested master at all. I have the fixes merged into my git tree: https://github.com/dragonian/mythtv/tree/fixes/0.27 " Patch - Bug Fix closed minor 29.0 MythTV - Audio Output 0.27.5 medium Fixed 0
