KD-75XH8096BAEP After firmware update Firmware update to v6.4770 from Sony's site

ARC functions don't work for me ....... Can't be heard when I play YouTube ... Netflix ..... and the like
However ... when I turn on the TV the receiver also turns on ...... When I turn up the volume from the TV's volume control system the receiver ...
But to hear YouTube \ Netflix I only hear with If connect an optical audio cable.
Of course, before the update, everything worked with the HDMI as the optical was not connected at all.
I've tried all the solutions found on the site, including both Factory and Power reset.
Disconnect Power .. and waiting over 2 minutes from the TV also from the system.
My audio system is also a Sony STR-DH790B

Hi,

That sounds frustrating. I had a quick search, all I could find was a subreddit discussing a similar issue. As a workaround, someone found that turning on the amp/receiver a few seconds before the TV helped.

Clutching at straws probably, but worth a try.
