Dolby Atmos is up to 12 channels this connector has 16 + ground

It’s clearly for Dolby Atmos + component video with an inline microphone

The most complex Atmos system you can build is 24.1.10 so that’s 35 audio output channels. Sure the audio is packed in on disc in 12-16 channels. But Atmos is object based so the Atmos can calculate where the sound should play across those 35 speakers.

I was aware that there was algorithmic expansion that could be done, but I did think it was a maximum of 12 real channels (L, C, CR SL, SR, RL, RR, sub, 4x overheads)

What are the other 4? Do they add channels between the ear height and overheads?

I think those are the pure object based channels that a TrueHD receiver can’t use. So that’s for audio sources that will be added across the other channels.
