I Have a Arc SL attached to a 65” Samsung TV via HDMI ARC.
Our Sound bar shows this issue usually a couple of weeks after plugging the SB out for 20s and plugging back in. This has always resolved the issue for a couple of weeks and then the issue comes back. I have been on to Sonos support on 4 separate occasions and also provided the diagnostic events - No Joy. Very frustrated considering this is a very expensive SB.
Firm wear - Fully Updated
HDMI Cable replaced : Issue reoccurs
Support suggested changing the WiFI channel, no impact, issue reoccurs
