eARC HDMI Audio Extractor - Extract Dolby Atmos to Sonos Soundbar

If I configure it this way, and I have a smart TV like a Sony Bravia with eArc support connected to the eArc port on the extractor, will the audio form the TV get passed to the Sonos soundbar? I need to make sure the audio from TV apps and the other TV inputs can continue to pass to the Sonos soundbar using this unit. I also have an external input I need to get audio to the soundbar as well, but I also need to make sure the current functionality, of TV audio -> Sonos over eArc will continue to work. Please confirm and thank you! If this will work I will buy this right away.

can i use it with apple tv to sonos arc?

Any plan to launch it also for 8K (4K/120)?

love from India...❤ .... i am your big fan.....😊

Will this also pull the audio from the eARC from TV apps and output on the Audio Only HDMI to an older receiver?
