I’m just wondering if it would be possible with future software updates to use a Sonos amp to get a full Sonos Dolby atmos setup? It seems that you can already use the amp in a 5.1 setup to provide the rear speakers (using 3rd party in ceiling speakers) so why not use it to provide Dolby atmos to the in ceiling speakers (either 2 or 4) instead with a pair of play:1’s providing the rear channels.
Apparently atmos can only be passed over hdmi and not optical but now that the beam connects to the tv with hdmi through the arc port doesn’t this make this idea more feasible.? im sure Sonos could produce a Dolby atmos specific in ceiling speaker so that the speakers audio qualities were known so that true play tuning could be used.
The ideal setup would be beam (or updated playbar with hdmi/arc), sub, 2x play:1 as rear channels, and amp which would be a wired to the in ceiling speakers and configured to provide the the “atmos” in ceiling speakers and grouped with the rest of system.
There are too many variables with ceiling heights etc.to get a good effect from upward firing speakers so I think this would be a great solution from Sonos and I’m sure there would be plenty of demand for it.
