Thanks! If Sonos would get their a## in gear and fix their android app to work on Chromebooks, I'd be all set. 99.9% of our interaction with Sonos is via Alexa. And the primary use is still TTS. I suspect a physical remote would just get tossed in a drawer somewhere and forgotten, so I haven't bought one --even though I love tech gadgets. BPTworld's Notifier Plus app allows for volume setting before & after the TTS, btw. I've modified the Notifier Plus Child app code to be more useful to us. I've also added a virtual switch to disable all problematic TTS rules & apps with the idea being that we'll just kill TTS when we want uninterrupted music.
Though we rarely listen to music, parties & holidays are an exception. The problem I AM having is that an incoming TTS causes the music playlist to stop and it does not resume. To counter that, I purchased a third Sonos to be used for music only. My plan is to use it mostly for outdoor gatherings or in remote parts of the house (garage) . I can see where a physical remote might be handy there --but, then again, there's always a Dot nearby and Louise tends to default to voice control.
