I found my culprit. It is my Samsung 4K UHD Blu--Ray player UBD-K8500.
By process of elimination.
Unplugged and powered down everything, including soundbar, TV and Router and all devices connected to them. Then power on and connect one by one. Anytime I connect the Sammy BD player to the TV (it has the Main HDMI port out to the TV HDMI Input #1
for video, and HDMI Audio Port Out to the soundbar), the Bravia Sync and ARC channel do not work. Everything else connected to them (soundbar, Amazon FireTV, Directv Genie HR44, TiVo) both ARC and Bravia Sync work fine. Go figure.
Anyway, the good news is that my Bravia TV is not broken and no need to replace it. Somehow, the Sony TV and Sammy UHD BD player do not like each other. Now it has to be my decision to whether only connect the Sammy 4K player to tV when in use, or keep it on all the time and do without Sync and ARC...
Hopefully others will take note, and Sony and/or Samsung will fix this issue with a software update.
