Sonos ARC > Sky Q > Lip Sync Issue

48 replies

Hi,

I have recently swapped an old 5.1 system out with the Sonos Arc. The 5.1 system had all components connected into the A/V receiver with one HDMI from the receiver to the TV (Sony Bravia KD49XE8005) and had absolutely no lip sync problems.

I’ve now set up the Arc (via ARC) and, I thought, everything was still fine. I had no lip sync issues on apple TV, PS4 and some Sky content. Sonos Arc is connected via ARC (HDMI 3 in my TV’s case) with the Apple TV, PS4 and Sky Q box connected via other HDMI inputs.

However, I have identified a very specific issue with Sky Q. When watching stereo content (i.e. non HD) I have no lip sync issues. When watching UHD Atmos content (output via DD+), there are no lip sync issues. However, when Sky Q outputs DD5.1 the audio and video go out of sync in the way that can’t be fixed (i.e. video is ahead of the audio).

I have tried a power cycle and the issue still persists. Additionally, when I set the Sky Q HDMI output to normal and it outputs in stereo the audio and video are in sync.

I really want to find a solution to this because the Arc sounds great and Atmos content is brilliant, but lip sync issues for what is likely to be the vast majority of my TV watching is a bit of a deal breaker!

Any ideas?

Thanks for your help!

I have the exact same issue with my recently purchased Philips OLED854. The Same set up with my previous Samsung Tv did not exhibit the problem at all. My only solution is to change the skyQ sound output to “normal” which kinda defeats the purpose of having a Dolby digital/Atmos sound bar. Logic suggests it has something to do with the way the tv is processing the Dolby digital signal which adds a delay. As the sound is behind the picture there are no adjustments via the tv, skyQ or the Arc that can help.

I feel your pain :(

After a ridiculous amount of research and a visit from the sky engineer, there’s nothing that fixes it. It seems to be something to do with the DD signal from Sky Q, it’s a pretty well documented problem! I even looked at returning the Arc and getting a different soundbar with multiple HDMI inputs so I can plug loads of devices directly in, but there doesn’t seem to be anything that does that and has good reviews.

What does work is plugging directly into the Arc via optical. So for now, I’ve resigned myself to an optical signal with a switch to plug everything into. There is a HDMI product called the Arcana from HDFury that will resolve the problem and allow full Atmos signals but is not available until October.

I think you have hit the nail on the head so to speak

A new TV with the ability to pass through the codec to the Sonos and eARC technology should solve the issues

There are some good TV deals on at present Especially this Friday😄

I have solved my lip sync issues with Sky Q 2TB Samsung Q80 series 2020 model and my Sonos Beam , Sub 2x SL2

Set all sound delays to zero on all three devices

Sky HDMI to Dolby Digital

Then on the TV in Sound Settings -Expert

HDMI -eARC Set to Auto

Digital output audio format to Pass-through

This last setting I think is the key to solving the delay

While not an expert I think this then allows the audio signal to be processed by the Beam and not the TV

The TV processing is causing the negative sync

Hope this may help

Thanks Jessica, boom 💥 sorted since you said “HDMI -eARC Set to Auto” i followed your instructions and it worked. I’m using a 4K Sony KD65A8 OLED and was pulling my hair out with arc lip sync issues with Sky 2TB box.

I actually have the reverse problem but with a Sonos Beam and subs. Sky Q UHD into Sony AF9 into Sonus Beam. Audio is actually before the video and there isn’t enough delay adjustment in the beam to totally get rid of it.

Sky Q on TV speakers is fine. internal TV tuner on internal TV speakers is fine. Either via Sonos Beam and audio is early.

Not sure how long it may take to be fair, at least the right people are now aware of it and starting to work on it 😁

Hey @RichH3nson , 🙋🏻‍♂️

did they ever get back to you on this issue, just keep seeing more and more complaints about it, Sky never seem to address it in any updates.

I tried the people I knew at Sky, but not heard any positive information back.

After doing the rounds with some of the test/audio folks they’ve all said that it’s down to how the tv handles the decoding of the signals.
If it was affecting all tv’s then potentially it could have been their issue but because it only happens on certain models and they’ve not changed anything the whole way through they say it’s down to the tv manufacturers. They’re still looking at other things though.

I have both Philips and LG and it doesn’t happen on either. The Philips used to fall behind a little when it had been paused for a while and rebooting the tv fully sorted it, after an update it’s been fine ever since.

Thanks for the update, seems a bit weird that it happens with multiple different TV manufacturers / models and in my case, at least, not with any other devices connected to the TV, Sky Q is the only common item across multiple brands of TV and sound bars that I have tried since getting Sky Q in 2016. Philips, Panasonic, Samsung TV’s, Yamaha, Playbar, Beam and Arc sound bars.

True, this is the exact kind of evidence I’ve sent across to the test team.

They’ve said they’re still looking into different things but it’s not a quick process unfortunately
