2 channel PCM from Roon to AppleTV shows up to the A16 incorrectly as Dolby Atmos only triggering the L and R front speakers, and can't up mix..
Dolby Atmos from Apple Music phone app shows up to the A16 correctly as Dolby Atmos.
Dolby Atmos from Apple Music Macbook app shows up to the A16 incorrectly as 2 channel PCM. At least it up mixes to Aura 3D.
Very confusing. Lol.
There are some inexpensive Roon endpoints available like the FiiO SR11 and from WiiM. Maybe try one of those? Some of them have digital outputs that you could connect to the A-16. Personally, I don't find upmixed two channel very satisfying and prefer to just keep it two channels most of the time.
