Sky puck lip sync issue

[kendoe47]

Hi All, I have got to admit with the latest update everything is now working fine. No issues what's so ever.

I had this issue on Sky Puck, there is an adjustment in 'settings-picture and sound-sound-digital audio delay HDMI' from there you can adjust the delay in increments of 20ms, worked for me (increased 40ms)

Same as everyone else, Sony Bravia tv, Bose Smart Soundbar and the puck, have it on have it on auto setting.

Has been nothing but problems, not sure if the new Apple TV continuous audio connection is what we need.

Onto my playlist first this morning something on Channel 5 and it started using the tv speakers again with the lip sync problem.

Got it back onto the soundbar, there is a very slight sync issue, Apple TV is brand new so hence suspect the puck at fault.

The Apple TV continous audio connection will have nothing to do with how your Stream puck sends audio to the TV. 

Try setting the puck's audio output to Dolby Digital+ or passthrough and see if that makes any difference. Make sure you use a high speed HDMI cable between the eARC ports on your TV and the soundbar so that full bandwidth audio can be passed.

I think the point was that if Sky were to implement a continuous audio connection similar to the one Apple have just launched, that might solve the issues.

I doubt it. tvOS merely wraps different audio formats into a Dolby MAT container for continuous audio on the Apple TV box. 

Stream pucks can convert audio to DD, DD+ or PCM and output that single format continuously. 

The lip sync issue is more likely down to the added latency introduced by the server-based SkyOS. The puck has limited RAM and can struggle to maintain accurate sync when a lot of data is coming down from the server which it has to process and output.

I have the same issue. Audio often get's out of sync. I have to go into settings, increment the audio delay to 20ms, then back to 0ms for it to get back in sync again. Happens almost every time I am watching TV. I have a Sonos soundbar, but I've observed this happening on the TVs speakers too. I don't understand how this is still an issue 2 years on.

I am experiencing constant issues with my Sky Stream device. This is the 2nd device, sky already replaced it because of this issue. 

The audio on almost every session get's out of sync. I have to go into settings -> audio delay -> 20ms -> back to 0ms to "fix" it. My setup is fairly trivial, I just have a Sonos soundbar. All other settings are standard, but I've tried different video/audio outputs and nothing helps. I'm also running the latest firmware. From what I can see on the forums this has been an issue for over 2 years now. I cannot understand how this hasn't been solved yet.

Have you tried replacing your HDMI cabling? Since moving all my A/V devices to the same brand, length and spec of certified HDMI 2.1 cable I've had no issues with lip sync on any of my HDMI connected devices.

I have not. Thank you for this, I will order a couple of decent 2.1 cables and try that.

You don't need to spend a lot of money on them - I got four cables for less than £10 each from Amazon. 

Hope it works for you!
