Not sure of this has been asked already.
My set up Sonos Beam Gen 2, Sub Gen 3 and pair of One SL
PC Windows 11 - Ultrawide monitor.
I want to connect my RTX 3090 GPU HDMI to HD Fury Arcana HDMI 2.1 HDMI-in and the Sonos Beam Gen 2 to EARC-out, but not connect the other HDMI-out to any display as I will be using the display port from my GPU connected directly to an ultra wide monitor.
Will the sonos beam work in this set up without a display by using a Nvidia control panel to select HDMI audio only
My goal is to be able to play games in Dolby Atmos with Dolby Access software from the Microsoft Store.

I’d think it would work, under the assumption the PC is able to provide a signal to both the HDMI output and the display port simultaneously.
The Arcana would take the HDMI stream, split out the eARC signal, and send it to the Beam. It shouldn’t matter if there is no screen attached to the video output.
Your question isn’t really a Sonos question, it’s more applicable to your PC (and their software) than it is to Sonos.
