Re: QS025 Lip Sync Issues

@Pukkajim  Try setting your Sky Stream Box to Passthrough, that should allow your soundbar or Amp to decode the audio and give you Dolby Atmos, or whatever audio format you prefer. 

Passthrough tells the Sky Stream Box to keep it's paws off the audio stream and do nothing with it, like introduce audio delays!!!

Re: QS025 Lip Sync Issues

Hi 

 

thr sky stream box seems under powered processor or ram etc

 

apple tv dolby vision atmos cuts out all the so I have to use the Sony tv owns app. 

to get lip sync to go away particularly on sky sports uhd i set up as follows with latest type of hdmi cables from ugreen.....stream sound setting is pass through

 

Steam box into soundbar then hdmi arc out of soundbar into tv. 

strips out the sound before sending video to tv.

 

unless new hardware comes out once my contract is over I'll not keep sky stream. I will either go back to virgin 360 (not their version of stream) or not bother and see how I get on without sports.....

Re: QS025 Lip Sync Issues

This is correct, this is caused by lack of processing power and will never completely be fixed with software. Passthrough has certainly helped.

Re: Voice not in sync with picture

Thanks but this was the first thing tried.  Initially this did work at all.  The second thing tried was to unplug it for a few minutes and then try again.  This was more successful but of a period of an hour it would soon go out of synch again.

 

the setting have no effect either.  Nor did a factory reset.  Sky sent an exchange puck but this also failed to work.

 

Sky then suggest I set the Broadband router to 2.4Ghz instead of its static setting of 5Ghz (because the router is close to the Sky puck.  But this is counterintuitive as this setting is generally used for devices further away).  Regardless I will try this shortly.

 

I note there are more posts to read through with other things to try but frankly none of this should have to happen.  Sky apparently are unaware of any known issues with Lip Synchronisation so I'd encourage people to call them.

Re: Sky puck lip sync issue

Thanks for this.

I've tried virtually everything I'm reading a lot of posts in this thread. I couldn't quite work out what passthrough and PCM were.

Your post, however, confirmed that it was a setting within the Sky Stream puck and not on TV (or for others sound bar!).

 

I have found that by getting into the PAC sound option and changing the digital audio output HDMI to any other settings, other than auto improves the sync.

 

This will see me through without having to cancel the service while they find a fix to the software update.

Re: QS025 Lip Sync Issues

I've just noticed what a useless formum platform, this is.  When you reply to a post, it doesn't actually reply to the post at all it just sticks it as a new post at the end of the list without referencing the post you are applying to.  I assume the person gets a notification saying there's been replied to, but then have to go and find it 😞

@No10 Using the forum is a learning curve and as far as I know it it not explained anywhere.  Hopefully the following will help you along for future posts.

 

If you click on reply to a post and then type @ you will get a list of contributors to the thread with the person you are replying to at the top of the list.  Just click on the one you want to reply to.  Also if you click on the quote marks ( ")  in the reply menu it will copy the post you are referring to.

 

I have done both in this post to show examples. 😀

Yeah they always go through the connection variable but this is nothing to do with broadband connection,  bandwidth, Wi-Fi etc. If it was the tv program would stutter or just freeze and give poor/loss of connection messages, not have the video out of sync with the audio, makes no sense.

Re: Sky puck lip sync issue

I've recently only had lip sync issues, I haven't added any hardware or changed any setting on my setup. It happened without any fault of my tv unit. This can only be a fault with Sky stream. However, I seem to have corrected the fault with a change to my tv sound controls from 'Bitstream' to 'PCM'. Once you have done this the tv resets and it should resolve the issue.

Re: QS025 Lip Sync Issues

Ok so i have switched to stereo, does that properly handle Dolby Atmos?

Re: Lip sync problems with puck

Hi, had same problem- tried everything in help section, setting and reset puck. The only thing that fixed it is changing sound to PCM stereo. (actually better sound for speech) . Was about to request a new puck.

Re: Sky puck lip sync issue

In view of the discussions over the last few days I thought I'd better check on the lip sync situation. I have my puck hard wired to the router and by HDMI to a high end Denon AVC. Lip sync has been a problem but became more stable a couple of weeks ago. On checking the sync is perfect. Even watching without the AV surround being used, it does go through the Denon when using the TV speakers and again no sync issues.

 

However when watching Ch5 earlier this evening the puck decided to go to BBC iPlayer and would not respond to any of the controls on the remote. I was about the disconnect it from the mains when it shut itself down and restarted. How's that for a curve ball!

Re: Sky puck lip sync issue

Agree with the above issues. Had Sky Stream in the same setup (Samsung TV, Sonos Beam) for over a year now and no problem. Around a week or so ago, sound is now out of sync with the video. Tried a few of the suggested workarounds but no fix. Reading everyone else's issues surely this must be due to a software update...

@SkyLimit I have to agree that this is a recent issue but whether introduced in the last firmware change or by an issue somewhere in the servers is less clear as my pucks updated to QS025 some weeks back and I only noticed a lipsync issue on multiple feeds a few days ago..

 

I tried various work rounds and found choosing "pass through" as the audio output on the puck is the best option for my set up.with an AV amp connected by ARC.
