Soundbar sporadically turns on in standby #50

The processor inside BRAVIA wakes up several dozen times over the course of one single night (see #9). Those wakeups might also cause connected HDMI devices to turn on. In this case it is a Teufel Cinebar 52 THX connected via HDMI3/ARC.

This however only happens when also an Apple TV 4K is connected to HDMI2, being an always-on device. It looks like those wakeups somehow trigger the Apple TV 4K (even though the LED stays off) which in turn triggers the soundbar.

This problem can more easily be reproduced the following way:

Put all devices (BRAVIA, Apple TV 4K, soundbar) in standby. Now unplug and replug the HDMI cable between BRAVIA and Apple TV 4K. Soundbar now turns on.

Enabling Remote start seems to have a negative impact for some reason.

This problem might also be related to #8 where the TV switches input to HDMI3/ARC after turning it on which also only happens when the Apple TV 4K is connected.

This is still a problem... My soundbar keeps turning itself on, even though the TV doesn't. So clearly a CEC handshake being sent to connected devices when the TV is in standby. This is a big problem for me, as it keeps draining the battery on my soundbar wireless speakers. I am using the latest firmware for the KD-65A85, released in end of November.
