I have a 4660RW Roku Ultra and I am looking to purchase a Dolby Atmos soundbar. Does the 4660RW support Dolby Atmos digital audio out via HDMI?
I've been trying to get atmos to work for months now but have not been. Can't find consistent information online. At this point I'm convinced it does not.
Going to buy the Amazon stick 4 . Half the price and it does support Atmos. And Atmos music via Tidal too.
Good luck.
I found my answer by testing. 4660RW does NOT support Atmos. Latest 4670R support Atmos for supported channel and content.
