I have read through some of the topics about this already, but most don’t seem to give a solid answer on projectors that do have HDMI ARC.
My plan originally was to get the Sonos Playbar+Sub+Ones with an HDMI switcher (for the optical audio) to go to the Optoma Cinemax P1 UST projector. I just learned about the ARC and it’s Dolby Atmos compatibility. The projector has HDMI ARC and states compatibility with Dolby Atmos. However looking through the forums, I’m not seeing a solid answer on if and how it would work with a projector that does have HDMI ARC (not eARC though). We would most likely only have 2 inputs to the projector anyway, so I don't think we would need an HDMI Switcher anymore.
Can anyone provide some insight into this?
