Thank you for your response and suggestion. However, I’m afraid I don’t allow any actively listening voice assistants on any of my devices or any in the household. I do use Siri from time-to-time, but only in the mode in which I have to explicitly activate her via a button press. (Yes, I know that if Apple were truly evil they could be listening at any time but, referencing Dante, I place Apple on one of the higher circles of hell… )
Thanks again!
There is a tone that can be enabled if you have a voice assistant installed on the speaker - the tone though is for use of the VA wake word, such as ‘Hey Sonos’, or ‘Alexa’ etc.
So, as an example, you could wake the speaker from sleep/or powered off state and use the VA wake word and listen for the tone.
The Sonos Voice Assistant tone is enabled by default and cannot be switched off
The Alexa/Google Asisrant tones can be enabled/disabled in ‘Settings/Services & Voice’ in the Sonos App.
My thoughts are you may perhaps find this will resolve the issue of knowing whether your device is awake, ready to play etc.
