TV and Sound bar Level Displays

[MGB_Bloke]

In Nov 2020 I purchased a Sony Bravia KD43H8196 TV and HT-G700 Sound Bar as a package. Since then, I have had a problem, not a showstopper but nevertheless I find it annoying and have tried to get a solution from Sony Support since purchasing.
Basically, when using the small sound bar controller, I get a display of the volume level on the sound bar and no indication on the TV screen which is what I would expect.
If I use any other controller (the supplied TV controller, a Virgin Tivo controller, a DVD player controller) I get a volume display level on the sound bar but also a different sound level display on the TV. This is independent of the service I use whether HDMI or Internet (e.g. You Tube).
Sony have been unable to solve this so far and have suggested that it is a software problem and that’s how it should work.
My questions are …
Has anyone else had/got this problem? Have you fixed it? If so how?

Hi @MGB_Bloke 

As my user name suggests I have using Sony TVs with Sony AV Amps and Soundbars for a considerable time. All I can say that it is “normal” for Sony to display the volume double on the TV than on the AV Amps and Soundbars. If Sony haven’t “fixed” this in over 30 years then the chances are they don’t care. Obviously for me this is the status quo but I can certainly understand how it could annoy new users. It’s everybody and every system, it is not just your setup.

Thanks for your reply - I was expecting that same operation as my 20 year old Panasonic system but seemingly Sony are "different".  There is another issue that is obviously not correct that I'm still pursuing with Sony.

A 20 five years old system cannot support HDMI-arc protocol so I assume yes, it behave differently... (not better anyway)

Thanks for your reply.

I have had an independent specialist look at the system and they summarise that there is a software problem on the TV such as it doesn't fully recognise the sound bar.

There is still a mismatch between the volume shown on the TV and the volume shown on the sound-bar.

I am also unable to fully reduce the volume below a certain level using the TV remote control ( I can mute) I continue to pursue this with Sony but I am minded to return the TV to the situation when I received the equipment and re-build it.  The sound-bar works as it should. I will continue to report Sony's responses if any.

Hi MGB_Bloke, let us know what happens with the investigation please. I've seen this specific enquiry before here but non of the steps I thought about worked.

For this specific "problem" I don't know who made the assertion that is a software problem, but it's wrong. There is nothing wrong with it, just the way it is.

Your tv most probably has a volume scale that is 1 to 100 while the soundbar 1 to 50, so when the tv is controlling the volume via HDMI -CEC it uses its own scale jumping 2 by 2 in sending the command to the soundbar (that is not able to manage 1 to 100). That is how it works also on mine 2013's HTCT350. Without the HDMI CEC feature (like in your old system) there is no data exchange between the two so you won't see anything on the TV display.

The second one could be some sort of problem in the communication, instead.

Thanks your reply to my question.  Did you contact Sony Support about your issue? I have been in touch for them for some months now about this.
