I have a Sonos Arc surround setup (Arc + Sub + Ones). I have NOT set up any voice assistants.
Randomly (sometimes in the middle of the night!), the Arc will say "hmm something went wrong, try again in a few seconds", literally at maximum volume.
Googling this phrase seems to point at a Google Home / Assistant error. Again, I do NOT have Google set up on any of my Sonos speakers. I do have 3 x Google Home minis dotted around the house, but obviously they should not be connected to the Sonos in any way.
Any ideas what may be causing the Google Assistant buried within the Arc to randomly activate?! It's pretty creepy...
