Audio Dropouts/No sound on Arc on XBox Series X connected to Sony 900H

I’m losing my mind over here :)

I have an Arc + Sub (gen 3) + pair of One SLs connected to a Sony Bravia 900h TV on the latest firmware with the 2.1 HDMI features. When the TV  is set to run at 60hz the sound works fine. When I switch the TV to 120hz my audio drops or I get no sound at all when selecting Atmos output on the Xbox Series X. Switching to Dolby Digital or 5.1 uncompressed works fine. 
 

Anyone else out there struggling with the Series X and the Sony 900h? I know Sony is having issues with this particular firmware version but I’d like to rule my Sonos system out as part of the problem.

This is a known issue with the Sony, they are working on it.

Not a Sonos or Xbox issue.

Anyone find a fix for this? Still finding the audio cuts out constantly with the series x but only on 120 Hz mode. Really disappointing as I bought the full surround set up to go with the series x.

If it’s just happening with TV audio, then perhaps look at the other connected TV peripherals to see if they are taking hdmi-cec focus. I would start by removing the other devices connected to the TV HDMI ports and see if the issue goes away, if so, then reconnect each device until you find the ‘culprit’. Then switch off it’s CEC control, or use a cec-less adapter.

That wont help, its a problem with this specific TV @120Hz due (I think) to VRR. Sony need to fix it, if they can. Hopefully they are not using the same defective Panasonic hdmi chipset that Denon/Marantz are broken by.

    I did try this to no avail, thanks for the suggestion. Behaviour is identical even when it's only the arc and Xbox hooked into the tv.
