This worked for me!! I changed the default to my "all" group (my only
one, since the Sonos fiasco) and then set it back to the hub. I stopped
casting and restarted and audio started coming out of it! Now fingers
crossed it'll actually keep working.
Mine started doing that 2 weeks ago, and a fix on another form page to
reset your devices. I reset a few but it didn't seem to work for me.I
sent feedback using the"ok Google, send feedback" function and within 24
hours, it was fixed. I don't know if...
