Earc tv to Earc switch

I am planning to change my setup on the Sony Bravia A80J. Currently, I have signal issues, likely caused by the Hue Sync Box, so I want to remove that and connect my consoles directly to the TV.

The problem is that the TV only has two HDMI 2.1 (120Hz) ports:

HDMI 3 (eARC) - Currently used by the Sonos Beam Gen 2.

HDMI 4 - Currently used by the Hue Sync Box.

I need both of these ports for my gaming consoles to get 120Hz. To make this work, I am looking for a specific HDMI switch that has an eARC extractor/pass-through function.

My goal is to plug the Sonos Beam into this switch rather than directly into the TV's HDMI 3 port, effectively freeing up that port for a console while still getting audio. I don't mind losing full Dolby Atmos support; standard Dolby is fine, as long as I can still control the volume with my TV remote.

Could you let me know if there is a switch that allows this specific configuration?

Surely the Hue Sync box is a HDMI 4 to 1 switch, although 120hz and eArc support is dependent on model (4k vs. 8k).

I don’t think there’s any hdmi switch that will work the way you described. 
Imho the best solution would be to use tvs eARC port for the Beam and connect a 120Hz hdmi switch  to the other 120Hz port of your tv. So you will be able to connect your consoles to the switch an use them alternatively passing through the 120Hz signal to the tv.
