Apparently many people are having similar issues. I have the TCL Rocky 49” television with no sound bar or amp connected, just using the TV speakers. Every week I either have a sync issue or audio crack/break up issue. And every week to fix this problem I have to do a factory reset. Which means every week I have to re-set up my TV and connected devices, re-log into Netflix, Hulu, Amazon, PBS and AT&T app. Now, surely I could have much more horrible problems to deal with in my life. But really, I wish I had a TV that simply just worked.
