ARC lip sync

@p2cho what is the sound stage like with the sub with music? I find the sound slightly recessed, especially voices. 

@MSterling that is a good thought

I’m not having lip sync issues on my LG series 8 TV from internals apps, but some content from external ATV4k thats has a ‘just about tolerable’ lips sync issue.

In the interest of science, I found an option to ‘bypass’ sound from external devices, this can have the effect to output sound before the picture. You can then delay the sound in the soundbar.

You then have the option to delay the sound in the Arc.

There maybe a similar ‘bypass’ option on Philips or other manufacture TVs, check your users guides.

Also, if you are using Apple TV, it maybe worth running through this process:

If you replace your TV set, Apple TV, AV receiver, sound bar, or any other related component after you've synced, you need to run Wireless Audio Sync again. 

@Fezutwo watched a Atmos movie on sky q sounded ok...not that u could fully tell any difference tbh...overall so not overly impressed with the Arc...still cutting out on Netflix and YouTube even with TV set to multichannel bypass instead of DD+.  Will give technical support a call Wednesday failing that I may send it back and stick with the beam for now

Hdfury “arcana” will solve this problem 

I have a samsung UHD TU-8000 and am struggling with the lip syncing issues. I can’t seem to find a decent setting and depending on what I’m watching it appears different programs are differ early delayed eg between atreaming services and live tv. This is driving me batty at this point. Any ideas? Never an issue with the play bar which I have in my other Tv. 

Had similar problems with lip synch with the Sonos Arc connected via eArc to a Samsung QE55Q90T, along with a Virgin media V6 box. I have another older Samsung LED TV, also linked to a Virgin media V6 box, when I connected the Soundbar to that there was no lip synch issues. 

Tried various options covered in this thread, also some suggested by the Sonos helpline to get the Soundbar working with the new TV, none worked and was close to returning the Soundbar.

Looking at my new TV sound menu settings, under Expert settings saw for “Digital Output Audio for...” you have the option of Auto, PCM or Pass-through. Auto was the default setting and made sense, but when I changed the setting to Pass-through my lip synch issues disappeared.

I’ve just purchased the new Philips 805 and I am having the same problems with my V6 box. If I keep the settings on Dolby Digital there is a delay on the sound, if I change it to PCM the lip sync fixes but I only get stereo. This is so frustrating, is there anyway to fix this?

Although my TV is a Samsung, I left the Virgin V6 sound output to Dolby Digital when I made the TV output changes mentioned in my previous post, since then I’ve had no further issues.

Thank you for the reply. The problem is I don’t see any settings like that on my TV.

I am using a Samsung 55q90t, virgin tivo 6 box and arc.

The suggestion of changing the expert sound setting to pass through has worked, thank you.

I would like to understand any implications this may have to the sound?

Thanks
