Setup Sonos Arc with One SL and Sub Gen3 on my Samsung TV. Synced up perfectly with HDMI ARC connection and all working great. However for some reason occasionally after shutting down TV for the night, the next day the audio comes on and then stops for a second or so before starting again. This repeated continuously, unless I disconnect and reconnect the HDMI connection or reboot the Sonos ARC. rebooting the TV has no impact, so the problem looks like the ARC. Interestingly if I go to the Sonos Source I don't get any signal from the Sonos when the issue is present? However when it's all working properly, I get signal okay and see the Sonos curved lines screen.
