Interesting, I don't see anything specific about ATMOS added in the commit history for LAV filters on github, so I'm wondering if we unknowingly have ATMOS bitstreaming capability via one of the recent ffmpeg updates (which LAV filters would also have).

When you see ATMOS lit on AVR is there anyway of telling what exactly you are getting? as no one on the Team has any ATMOS capable kit to do testing.

I don't think Atmos necessarily requires any special support for bitstreaming, we can handle it just like any other TrueHD stream, i.e. we just pass the entire stream on the HDMI link. This is based on the fact that existing "non-Atmos" Blu-ray players can passthrough Atmos as well without firmware update.

I have no proof, though, but if someone's receiver says it is receiving Atmos with Kodi (and says it is not receiving Atmos with non-Atmos TrueHD content), I'd say it works.

The patch mentioned earlier in this thread isn't really Atmos-specific, but a "general bug" in the TrueHD parser that mostly/only affected Atmos streams.
