HT-X8500 A/V Sync button not working

andyodell — Fri, 18 Dec 2020 15:34:37 GMT

When I first set this sound bar up the A/V Sync button worked as expected, but not when pressed all the lights on the sound bar light up as if it is disabled.

The TV is a KD43XH8505

Is something set up wrong?

No ideas? I think I've tried everything but don't know what was different to the first time everything was connected.

I'm not sure I undertand the issue, what do you mean by "button woks as expected, but not when pressed"

Sorry that should be "but now when pressed".

So it worked at first, but now when I press it all that happens is all the lights on the sound bar light up.

The manual explains that a certain number of the LEDs will light up depending the setting which is pretty normal. Check page 24:

I understand this and I used to be able to cycle through with the lights showing what setting it was on, but now all that happens is all the lights light up.

Have you tried a factory reset?

Re: HT-X8500 A/V Sync button not working

Yes I have tried that. It must be a setting on the TV perhaps which has changed something?...

Apart from the LED behaviour, is there a problem with the A/V sync?

I don't think the TV can affect that aspect of the Sound bar.

Yes it is sometimes very slightly out which is how I noticed that the function no longer works.

I was playing around earlier and I did get it to work again by swapping some HDMI's around. This was by plugging the V6 into eARC and HDMI1 into the sound bar, which is wrong as the V6 has 4K etc and the sound bar should also output Atmos etc using eARC?...

The set up (with the function not working) is as follows:

V6 -> HDMI1

HDMI3 eARC -> eARC on Sound Bar

How about toggling back and forth between the 2 options for HDMI signal for that input (HDMI 3)? (Settings - Watching TV - External Inputs - HDMI signal format)

Also check that Bravia Sync is enabled (Watching TV - External Inputs - BRAVIA Sync Settings) as some users reported it affects ARC operation on the forum before.

Thanks for the suggestions. I have tried this though along with the other input, signal and sync settings.

Have you tried toggling eARC On/Off? (Manual page 28,29)

Yea I had tried this. Shouldn’t it be best left on anyway?

Deinstalate Tune-In from Google Play and everything will be OK.

This isn’t installed

After reading the thread, I don't see a way that the TV might affect a function on the soundbar. Did you try changing the HDMI cable? Or try the bar with anther TV if possible? Hannah

Yes I have tried with another cable and it was the same. It is just strange that it did work for a few days and now it does not.

The only way I can get the feature to work again is by plugging the HDMI into the standard HDMI port on the sounder and not the eARC port, which isn't want I want.

Hi Andy,

Hope you're alright. It's indeed strange that this happened out of nowhere, but my focus is on the real immediate issue which is lip sync. Are the AV Sync settings enough to mitigate it?

The only way the lip sync seems to be ok now is by the following settings:

Display & Sound/Audio Output

A/V sync - Auto

eARC mode - off

Digital audio out - Auto 2

Changing any of these throws out the lip sync.

Is it a waste though to have eARC mode off?
