How to get Full Lossless Dolby Atmos for Sonos Arc & Sonos Beam Gen 2

OREI eARC 4K 60Hz Audio Extractor Converter 3x1 Soundbar 18G HDMI 2.0 ARC Support - HDCP 2.2 - Dolby Atmos Digital/DTS Passthrough CEC, HDR, Dolby Vision HDR10 Support (HDA-935)

Not the same as normal HDMI splitter. HDMI eARC and ARC carries sound through a seperate channel, not the regular channel over HDMI. So a soundbar that takes in sound via an eARC or ARC channel is only going to accept sound on those channels and not the regular HDMI sound channels.

The OREI eARC switcher is a eARC compatible switcher with 3 input ports. It took 2 years to come to this. I am sure there are other models out there. Maybe get a new TV. In 2-3 years time, when you change a new TV, it is likely to have an eARC port and have Atmos processing capabilities. But note that you will need to have Atmos too. Not just eARC.

In the meantime, does this work?
Yes. Atmos shows up.

What you need to do on your TV. Play around with the setting. Bitstream, not PCM. Pass through selected. Input vs output. PCM, Dolby Digital, Dolby Digital+.
