Sky Q box, LG tv (newish) and a Sony soundbar which around 3 years old and audio is out of sync by quite a bit (half a second or so at times).

I've given up now playing around with sound settings on the tv (sound bar doesn't have any settings as such) and it's driving me mad now.

Sound bar is connected via optic cable from TV (have tried running it direct from sky box but no joy). Sometimes it's more noticable than other times.

I'm sure I didn't have this issue before I got sky.

Any help appreciated before something goes through a window!

Thanks.

Just to add - using built in tv speakers it's fine but can't cope with the crappy quality!

My Daughter complains that her sound bar is out of sync so i'll be interested to read some replies,

Coincidently she has a Sony sound bar with SKY Q & an LG television.

None that I can find, only on the tv settings - AV sound sync that you adjust but can't get it right.

You should find an option for this on the TV.
My new LG OLED did the same, but there are various sound settings to correct it.

The real problem comes when the sound is delayed, and all the adjustments you have available only allow even more delay.

The problem I've got is the audio sync is inconsistent, some channels/programmes seem fine, others are out where the sound is too advanced.

I'm sure it's all down to the sky q box but there's no sound settings..

My LG soundbar and LG TV have this issue. The soundbar has a button for "speeding up or slowing down the sound" but still cant get it to sit right.

Given up and only use the soundbar.

Tosslink or optical cables are fine for audio but in my experience don't work very well for audio visual.

The signal needs to be converted to light then un-converted at the other end and this takes time and can cause the time alignment issues.

I've been through this in the past and spent ages trying to get the time alignment right but never managed it. In the end I upgraded my kit to take the tosslink out of the equation.

My advice is to try and interconnect everything, wherever possible, with HDMI cables for audio visual stuff.

General advice is to connect the sound bar directly to the Sky box to take the telly out of the equation. I would use HDMI if your soundbar has video pass through to TV.

Sky Q boxes definitely do have sync delay settings but they're no good if the sound is behind the picture. I generally have all the video processing on my TV settings turned off but you could try turning that on to delay the video a bit if it's in advance of the sound.

If there's a variation in delay then it may be down to the different times it takes the sound bar to process different sound formats. In the Sky Q settings there's audio stereo surround options sometimes disabling Dolby Digital plus or selecting other options helps.

Have a look at the Sky help forums, there's loads of help on this issue there.

Connecting the fiber to the SkyQ will certainly be the first step to seeing where the problem is (but you'll probably loose the ability to adjust the volume from the TV remote = unhappy wife).
Is sound in sync when watching normal Freeview from the TV?
Is it worse with HD channels (both from TV Freeview and/or SkyQ)

In my experience (with a crappy LG TV) it was simply that the TV didn't have the processing power to keep up with itself. Binning the LG (which had other annoying issues like the god awful Simplink system) and upgrading to a proper TV, a Sony [obvz] fixed all my issues.

Thanks for the replies. I'll look at all the above points and have another play. As much as I'd love to bin the tv that'll be impossible to get pass the misses due to a little one on the way..

From memory, yes it's worse on HD channels. TV is only 2 years old - I guess it's their lower end 4k picture spec wise.

I've also noticed adverts are usually really bad and the sounds even skips on certain adverts.

The soundbar doesn't have HDMI in or out, just optic and av (I'll have to find the cable and try that too).

You can set-up Sky Q remotes to control TV or AV Volume. mine controls my Yamaha Amplifier perfectly.
It's in the remote set-up section and walks you through it.

I have a samsung soundbar connected to a Sony TV via Optical and watch content via a PS4 connected by HDMI.

I notice similar sync issues but my soundbar has a basic tuning menu. setting "Audio sync" to -75ms (i think) sorted it.

In my case the tv doesn't do much, if any, sound processing. I have to do all the tuning via the soundbar. I can't even use the tv to change the volume.
