Sound problem

[Crescent1]

I have a Sony android tv kd49xh8096bu and Sony sound bar ht-zf9. Added to this I have a sky q box.

the problem I have is the sound seems to switch from stereo to mono, not all the time but enough to make it irritating. 
I can also describe it as the sound coming from the sound bar to then coming from the tv speakers.

also the info bar keeps dropping whilst this goes on, I fixed that by stopping the info bar in settings.

the tv is 5yr old but still within warranty (John Lewis) the sound bar is less than a year

any help would

Hi,

Can you please check if both devices are running the latest firmware?

Yes. Both TV and sound bar are up to date with downloads

How is the TV 5 years old? This model was released last year.

[Crescent1]

Sorry tv model is Kdx49xe9005

[Joe_Dohn]

No worries ^^

The latest version for this TV is v6.7140.

My tv says it’s up to date it has pkg6.7140

I believe the TV shows a notification whenever the audio output changes (something similar to "TV Speakers Active"), do you see that notification?

[Crescent1]

No there is no notifications. I thought it was my sound bar so I got a new one. Still the same.

As I was still in warranty, just, I got John Lewis to have a look. They changed the hdmi pc but that only lasted a few days. They are collecting the tv on Monday

the problem is intermittent and they find it difficult to pinpoint.

I have turned the info bar off as it was dropping constantly.
