That’s odd. The TV sends the volume command via CEC-ARC to the Sonos Arc. There really shouldn’t be any delay at all. Have you unplugged the TV from the wall for 5 minutes? Have you submitted a system diagnostic within 10 minutes of reproducing the issue, and call Sonos Support to discuss it?Don’t post the resulting diagnostic number here.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

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.

Most of the problems, I have ever had with AV equipment have been down to HDMI-CEC, every manufacturer uses a slightly different proprietary implementation and these when blended together, can cause strange cliches, try turning off all the attached device’s CEC.
