Yes, of course. You would say.
The CRAZY thing is:
- That a Sony soundbar (HT-CT790) ALWAYS has troubles with my Bravia (KD-55X8505C) over HDMI;
- That a Sony headphone (WH-1000XM3) ALWAYS has troubles with my Bravia over Bluetooth!
Sony is bad news, and Sony + Sony is triple the bad news.
As can be found here in the forums, please update all firmwares (tv by usb/internet, headphone with the phone app), and clear ALL Bluetooth lists/connections in tv and/or headphones. Reboot/restart all.
Use the app Bluetooth Scanner by ZD Works! Paid or Free.
It works WAY better than Sony's own software and after a lot of tries, I got it connected!
