I have a Sonos Arc Ultra connected via the HDMI Earc cable to a 2021 Sony XR-65A80J tv.  I’m using the Sony remote that comes with the TV.  When adjusting the volume there is 1) a delay in the volume response at the TV and soundbar, and 2) when adjusting the volume by multiple steps, it misses the input unless you press the button, wait, then press the button again.

Can this be corrected with the tv settings? Or is this a common problem across Sonos soundbars and Sony TVs that is still unresolved? 

I have same problem with delay. Sonos Arc Ultra connected to a XR-77A80J.


Have you submitted a system diagnostic within 10 minutes of experiencing this problem, and called Sonos Support to discuss it? Sonos uses CEC commands from the TV via the ARC signal to change volumes, there shouldn’t be any delay, unless the TV is not sending the signal at the correct time. 

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution. Especially if there is a software issue causing this delay. 

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.


Thank you for the suggesting.  I have not.  I’ll give this a try and see if they can identify a source and solution.
