I replaced an AVR using preouts with an AVP and started a series of persistent and yet random audio drop outs sometimes on all sources simultaneously, Apple TV 4K (new), Roku ultra (old and new), OPPO 203. No one from any forum or manufacturer could logically offer a solution. Go to solutions were to unplug everything, factory reset everything, reinsert HDMI connections to different HDMI inputs, its the eARC checking from tv so reinsert main AVP out to non eARC, buy new cables, make sure all cables are not 3 ft but 2-3 meters, etc. It calmed somewhat if I watched smart apps on the TV (out of necessity) and used eARC to AVP for sound. That seemed to have fixed it for 2-5 days but it always returned—more so on Apple TV. So 4 days ago I signed up for Apple tvOS beta plan and that update seems to have solved it—for at least 4 days now. What no one can explain is why if one of the sources is the problem does it also cause audio dropouts on the other sources even the oppo?? Common theme would be the LG TV (C9 2019) but all those possible CEC simplilink settings are off. Sigh. So HDMI seems to have ghosts that no one engineer or company team can solve.
