No there’s no way to disable it - but there’s certainly other ways to set a volume-level without hearing any beeps, such as via the Sonos App, 3rd party App, using a voice assistant, or even using a 3rd party hardware remote.

Thank you for the response and yes, if I use the app then the beep volume issue is ok, there are other situations where a good old fashioned manual adjustment is the easiest way to adjust the volume and it’s horrendous. A huge flaw if this can’t be adjusted in configuration.

You could put it forward as a feature request to Sonos, I guess. Here’s a link to contact them, if you want to put it forward for them to consider:

Will! Good suggestion thanks
