Continuous AV Sync Issues

[ToadyMcToad]

AV Sync/Lip Sync for UHD and HDR live TV and on demand is terrible. One day it looks ok and synced up, the next it's off, unplug everything and replugging it all in again sometimes works but not always. Honestly this is a disaster of a piece of hardware. I have 2 pucks, one is the original sky stream model and the other is the newer one. Both have this issue intermittently, but it is a problem more often than not. Both are ethernet wired in.

It's not my internet (consistent 70mbps and barely anything else using the WiFi), it's not my TV. Everything else plugged in is 100% in sync - blu ray, ps5 and streaming apps through both are fine. The old sky+ was fine too.

£100 a month for this trash is unacceptable.

It'd be nice that instead of taking fixes behind closed doors, potential resolutions could be shared since so many, including myself are suffering from this sync issue. 

what is the resolution Sky, please?

Also having same issue. It's clearly an issue with sky stream box as if you reset it, it improves but then after 5/10 minutes it gets increasingly out of sync. BBC channels are the worse for it in my experience.

How about UHD/HDR content on demand? This is where it is at its worst for me. Anything Cinema/Atlantic/Max/One/Showcase is nearly unwatchable at UHD or HDR, for which Sky charge a premium.

[ToadyMcToad]

Agree completely. Unfortunately I think this is a software issue and possibly a memory or hardware limitations.

It should be fixable as the puck definitely buffers content. E.g. if you connect via ethernet and turn WiFi off, start watching something on demand and then pull the ethernet cable it will continue to play for 15 seconds or so. It's therefore not an internet speed thing as my puck is clearly building a buffer. It's how it is processing the content that is the issue.

[Green_tree2828]

Agreed. Sky cinema on demand the sync is off by seconds.

For me I came straight from Apple TV 4K- literally a straight swap, same high speed hdmi cable just swapped Apple out for the Sky and audio sync issues right off the bat with sky but not with the Apple.

Same issue with UHD out of sync. 
Tested watching live Sky F1 on ch 407 in UHD which is out of sync then switch to ch 857 which is Sky F1 HD and no such issue. 
Q box rebooted - no improvement

Audio set to normal  - no improvement (same on all settings)

So it's a UHD issue on the Q platform.

There is something going on with on demand content vs live TV content. It seems the AV sync is different in the on demand player compared to the live TV player. It's pretty clear this lies with the puck. I have 2 different pucks, 2 different TVs (both high spec top end flagships) that both have AV sync capability to their internal speakers and also sync perfectly to the respective external soundbar with live TV and every other input thrown at them. This issue with the on demand player is replicated across both setups no matter how much I mess about with sound output settings, picture settings, passthrough etc etc.

This is CLEARLY an issue with the player technology Sky are using for their own content, whereby the technology is incapable of holding the audio and video in sync and output it as such.

REALLY tired of being fobbed off with is it your broadband, is it your TV/Soundbar set up, is it the HDMI cable etc etc. The stupid puck is the only common denominator that has AV sync issues.

Watching Amazon Prime in 4k HDR for the football tonight through the puck and there are no lip sync issues. Tried Fallout through the Prime app too just to see and that's fine. The issue is obviously the player Sky are using.

Sky - how can you seriously charge extra for UHD if your technology introduces basic errors to the processing?
