Hi all,
just to let you know if can help, I’m testing the PureLink CSC200 adaptor to have Dolby Atmos on my Sonos Beam2 connected to an old Samsung TV that has only an ARC HDMI port and, using as input a Fire TV 4K, trough the adaptor I can reproduce correctly Dolby Atmos on Netflix and Disney+ at a third of the price of the HD Fury ARCANA. Really fantastic!!!
