Do we have a proper fix for the Pro audio sync problems?

Matomo — Wed, 18 Jan 2023 12:16:40 GMT

The Pro box still seems to have drifted out of lip-sync every time I turn it back on.

This can sometimes be fixed by changing the resolution to 1080p and then back again.

Can anyone at BT confirm that a permanent fix this issue is being worked on please?

Nice active forum! OK do any of you have a fix that has worked for you?

Hi @Matomo your posts on the forum do not go directly to BT staff so most responses will be community members based upon their own knowledge and experience.A new thread will not have members already following as would be the case with an existing thread.

@Matomo Sadly the BT Pro Box is not so Pro as it would like to be, as you mention the audio sync problem is still an issue, the app support is very poor. I now only use my box for recordings.

A great shame.

I’ve had to whack the audio delay up way more than I imagined. Think I’ve got it on about 160ms now.

Seems to have done the trick, but I’m really surprised this hasn’t been fixed by now. Other than this I do think it’s a great box, I’m really impressed to be honest.

As for there not being any staff on this forum, well there definitely are!

@Matomo how are you connected up with the box?

For me it's all hdmi.

Probox -> Sony av amp - > Sony bravia tv

Before my amp upgrade, I had the box connected this way...

Probox - > Sony bravia TV - > Sony av amp old (connected to TV via optical cable)

My old method had lipsync issues, yet new method doesn't. Some who have soundbars and av amps connected via arc/eARC also had no issues either.

All HDMI to a new Sony XH9505. Then to my Sonos via HDMI ARC.

Does the sonos have a hdmi input?

If it does, see if you can try it that way.

BT - > sonos - > tv

See if the issue goes away. If it does then possible it could be something else.

It does have HDMI input yes, that’s how I’m getting the audio to it at the moment, I’m fully HDMI.

Worth mentioning that I didn’t have lip-sync problems with Sky, and I don’t have lip-sync problems with any other types of BT TV box. I’ve got them all and have tried.

Thanks for testing that. Certainly one for bt to look at.

Hope it gets sorted soon for you.

Based on my experience what sync issues? Is it maybe something to do with your setup?

Re: Do we have a proper fix for the Pro audio sync problems?

Matomo — Sun, 22 Jan 2023 12:38:51 GMT

Blimey! Plenty of posts about this on both this forum and others.

Not my setup no, Sky was absolutely fine with exactly the same setup.

How do you connect it this way? The bt box and sonos only has one hdmi port

Re: Do we have a proper fix for the Pro audio sync problems?

Matomo — Wed, 25 Jan 2023 19:13:04 GMT

Sorry, maybe I didn’t explain very well.

HDMI from BT box to my TV.

Then an HDMI cable from the HDMI ARC socket on my TV to the Sonos Beam.

That's my setup too. Bt box to Samsung tv. Earc port to sonos. Tried every adjustment to remedy and only solution is to switch bt box back to stereo. If I compare to the terrestrial channels on the TV itself, No lip sync issues.

Matomo — Wed, 25 Jan 2023 19:30:09 GMT

Yes same here. I have Freesat and Freeview on the TV itself. Both fine.

this didn’t happen on Sky with the exact same setup. Also doesn’t happen on the latest BT TV Mini box. It’s purely on the Pro.

I have an old bt dtr t2100 box. Plugged it in and tested if lip sync still exists. Sound perfect on terrestrial and stream/sports channels. Might just be placebo effect but convinced my sky sports football is clearer on the old box (stream channel)?? There isn't a haze that I always feel there is on the tv pro box. Maybe I've got a dud

My set up is the same as others.

If I select the surround setting the audio sync is awful, so have to switch back to stereo.

The lack of apps, the poor integration of ITVX etc, do we think Youview is on the way out ?

All in all a great shame, as the Pro Box could have been really good.

@nickmorc

Talktalk has got 'round' the issue by doing effectively what sony does.

They got a google TV box that runs Google TV OS. It has one special app though called 'youview' which is to access the ip/terrestrial channels.

However every app except Iplayer, itvx, and all4 are in the google side. Yes you do get apple tv, you do get disney+ etc etc.

Perhaps BT might have to go down that route. The box is untested on BT and I doubt it would work if one tried. (well the app via my sonyTV does nothing and thats connected to the internet as well)

Is anyone still having sync issues?

For me it’s got even worse recently. When I turn the box on it’s a good few seconds out of sync. The way I fix it is to into audio delay in settings, change it to a value, then back to 0. Then it’s fine.

I’m really surprised this is still an issue. Never happened with Sky+HD or Sky Stream.
