AF9 Lip Sync Issues Sky Q/Sonos Beam

Turnbacktime — Thu, 04 Feb 2021 15:31:55 GMT

Trying to get some resolution to ongoing lip sync issues with my SkyQ/AF/Sonos Beam system. SkyQ goes into HDMI 1, which is set to enhanced, and is configured for Dolby Digital for the audio output via HMDI. The Sonos beam is connected to eARC and the digital out output is set to Dolby Digital on the AF9.

To get close to acceptable lip sync I have to set the TV dialog sync setting to its max in the sonos app. Even then it isn’t quite right and what is more it varies over time. Can be watching one minute and it is acceptable, 30 minutes later it is noticeably out.

Watch SkyQ or AF9 internal sources on TV speaker and lip sync is fine. Watch Sky Q or TV sources using Sonos Beam and problem is the same on both. So to my simplistic mind it appears to be an issue with the way the AF9 is putting audio into the eARC signal. Or a config issue.

Any suggestions.

Hi,

The issue might be related to the different processing times of the audio signal in the various devices.

E.g. lip sync is probably fine with stereo signals but is getting worse with multichannel signals.

If possible I would suggest to connect the audio signal directly to the sonos beam to reduce processing time.

Cheers

Peter

That would be the opposite way round to the problem I have got. My Soundbar audio is early and I am having to delay it in the Soundbar settings to get anywhere near acceptable lip sync. I just can’t delay quite enough.

Also taking audio direct from the source only really works when you have just one source or you don’t use the Apps on the TV. If you also use say a Blu Ray Player and Netflix on the TV then you won’t get any audio.

Is the TV up to date: https://www.sony.co.uk/electronics/support/oled-tvs-android-a9f_af9-series/kd-55af9/downloads/00017127

Does the lip sync remain if you disable eARC and just use ARC?

Yes the TV is up to date in terms of software. How do you disable eARC and just use ARC? I haven’t seen anything obvious in the setup menus, but might well have missed it.

You can find that option under Settings - Display & Sound - eARC Mode.

Thanks, just tried it. Disabling eARC and running in standard ARC makes no difference to the lip sync. The audio delay in the Sonos is still cranked up to max and not quite there.

Have you tried using Optical instead of HDMI ARC?

Re: Betreff: AF9 Lip Sync Issues Sky Q/Sonos Beam

Yes. Optical from TV seems to be about the same as HDMI, ie I don’t have quite as much adjustment available as I need. Audio still a touch early even on max delay on Sonos.

Also tried various permutations of Dolby Digital, Digital + and PCM. All much the same,

If it's the same on everything maybe the issue is with the Sonos itself, have you tried the same connections with a laptop or another TV?

Sonus is fine when connected to the optical out of an old Sony KDL4000, on both internal TV tuner and Sky mini box.

It is OK when connected direct to optical out on SkyQ box. But that isn’t a workable solution as I have blu-ray and apps in the TV to that I use.

Also not sure what in the Sonos Beam would make the audio early.

I'm not really sure what in the TV would cause that either, it's just HDMI doing what HDMI does as usual.

Did you check out the new software update for your TV yesterday (v6.5042)? Maybe that will help.

No haven’t tried that. Will see if the TV will update later this evening.

It usually takes time for the TV to "see" the update, so you might want to give the USB method a try instead of waiting (unless you don't mind the wait).

Re: Betreff: AF9 Lip Sync Issues Sky Q/Sonos Beam

Turnbacktime — Fri, 26 Feb 2021 16:07:55 GMT

I will probably wait. Have never tried the USB method. I have just put the set into game mode. Will withhold judgement one whether it is detrimental to picture quality but does seem to have bought the lip sync within range of the Sonos adjustment window.

Do let us know once you apply the update. It'll be really helpful, especially for those who may come across the same issue in the future ^^

Will do. TV us still not showing it as available

Did the update about a week ago. It hasn’t done anything to improve my lip sync issues.

Hi Turnbacktime, try a factory reset after the update, it usually works.
