I bought used Sonos Beam (gen 1). Previous owner said it worked correctly. I mounted the device at home, pressed and hold the special “infinity” button until short sound received, to delete all the settings . Unfortunately it did not help. Sonos app on my IPhone does not find my Sonos Beam. So I cannot tune it, cannot use air play and voice management. Thank God it connects to TV via HDMI ARC well enough and TV sound plays on Beam correctly.
