I have a Samsung QE65Q7FNA TV and a Sonos Arc soundbar. When connected via HDMI-ARC it works for a while but then the soundbar stops being the audio output and the TV reverts to its speaker.
If I use optical connection instead this doesn’t happen but then cannot control the volume with the Samsung remote because it is not an IR remote.
From what I’ve read in other threads, this is a known issue for certain Samsung TVs and the Sonos Arc. Does anyone have any updates or suggestions?
