In which case the voice sync issue would also affect Apple TV, Fire TV and Virgin, which from other posts on here is clearly not the case. And remember, the issues here are not just voice sync, but also the periodic and momentary loss of audio signal which is just as annoying.
I am not convinced that this is solely a software issue - my suspicion is that the problem lies with the ability of the puck to reliably send both hdr video and Dolby sound simultaneously via hdmi without running into capacity limitations. I certainly don't see this as a tv problem - it doesn't appear to be either manufacturer or model related at all. And since it is also evident via both ARC and eARC, I doubt that it is related to implementation of either standard.
Interestingly I never experienced either audio sync or dropout issues with Sky Q which worked flawlessly for me. But then I suspect there are inconsistencies introduced by varying consumer setups which just add to the mystery! Part of the problem for Sky is that their hardware/software solutions need to be able to cope with the differences in subscriber hardware and set ups. But if Apple etc can do it, why can't Sky? And since the software is hardly unique, my suspicions are that this is a puck hardware issue.
