My Arc is connected to my TV (Sony XBR65X950H) while my Beam is not. The TV and Arc was purchased in January, while the Beam dates back to about 2 years.
About 3 weeks ago, I could no longer group Arc and Beam to play music or sounds from TV on Beam. When I group them to play music, it works for maybe 15 to 30 minutes and then the speakers stop playing. When this happens, Sonos App still indicates music is playing, yet no sound. If I select “stop” on Sonos App, I received a message that the App can’t be found. Also, when I group Arc and Beam together for TV sound, the sound on the Beam goes in and out. If I play music as a stand alone (without grouping them), both seems to work fine independently and TV sound using Arc as speakers has no issue. The problem occurs in grouping them. I also have Sonos One - when I group all of them, sound stop on Arc and Beam with music (No sound on Beam for TV). There is no Wifi issue when this happens.
I reset the Arc and the Beam numerous times and reinstalled the Sonos App, yet the issue still persists. In fact, after resetting the Beam a few times, I am now unable to add Alexa as a voice service. As a fix, I deleted Sonos on Alexa skills and re-added it back - it didn’t work- Alexa still can’t be linked to Beam.
Any thoughts?
