I’ve learnt a lot from you Over the years. Thank you and as a way of saying thank you , I’m posting conversation that might help others
Kept experiencing tiny audio drops (milli seconds) from rear speakers connected via s2 amp connected to arc playbar.
after trying everything , new ethernet, updating software, changing tv settings . But nothing
