I just got a Beam and the audio ducking when using Google Assistant is quite annoying. I understand that any currently playing media will have its volume lowered so you can hear the response of the Assistant, but this goes on for far too long after the Assistant has finished speaking. This also means it’s listening for additional commands, so it picks up any conversation during this period and tries to search for whatever is said which is frustrating.
I wish there was a way in the Sonos app to adjust this. I used to use a Google Home Mini which would duck the audio for the response, but then crank it back up to where it was as soon as it had finished speaking. If it can be accomplished on a device that is far, far cheaper than the Beam, then I’m sure Sonos can make it work.
