Hi when I activate input signal plus for my sony ht-a9 hdmi 2.1 soundsystem, I get a black screen and no connection screen. My TV is a brand new 65 s95c. 

I can't use my hdmi in ports on my soundsystem, without active input signal plus I'm limited to hdmi 1.4.

I changed cables and reseted the tv and soundsystem, but with no luck

My TV is on the newest 12.05.0 firmware 

Thx a lot for help, and sorry for my maybe bad English

@Dennis1981x: Have you tried connecting the sound system to another HDMI port e.g. HDMI ARC? When you head to External Device Manager > Input Signal Plus, are you making sure to select the correct HDMI input?

Yes it is connected to hdmi 3, i need earc.

Yes i selected the right port.

When activate "extended signal plus" on the right hdmi port the entire soundsystem no longer works, no sound ,no picture (can't enter the soundsystem settings anymore)

I got answers in the avs forum from users who have the same setup (sony ht-a9 sound system, samsung s95c tv) as me. These users have exactly the same error. The "extended signal plus" setting cannot be activated for the sony ht-a9 sound system. It is therefore an HDMI handshake bug. how should i proceed now? I bought the sound system partly because of its HDMI 2.1 capabilities. and without being able to activate the option, i can't even use hdmi 2.0 on the sound system. how can i report software bugs to samsung ?

apparently many also have the same problem with their pc that "extended signal plus" cannot be activated

Just to make it clear that I'm not the only one affected

This user here recommends deactivating "extended signal plus". But that's not an option for me.

I hope this problem can be taken care of.

Because apart from this error I am very satisfied with the TV

The problem is solved after a new firmware update of the sony ht-a9 soundsystem. Everything is working fine now
