I recently made this post and marked it as answered but it was by accident and I don’t know how to unmark it so forgive me.
I have an arc with a sub and 2 one sl, but over the past 2 weeks my arc will cut out when watching content in Dolby atmos. Sometimes it will cut out after watching for 5 minutes and other times it will take 30 mins to an hour to cut out. I have called and chatted with support several times to no avail. But if I reboot my arc the sound will come back again for 30 mins to an hour or sometimes if I just watch a non Dolby atmos show the sound will come back within a minute. I have an Apple TV 4K with a 55 lg cx but I have tried to watch something directly through the tv and the sound still cuts out. I also bought a new hdmi cable. I have also turned off a lot of devices to make sure the arc had plenty of bandwidth available and the sound will still cut out.
