Yes, I'm afraid it's the old chestnut again.
I've just upgraded from 1st gen. I had no problems as I was taking the audio out from sky Q into a toslink switcher via the optical adapter .
I upgraded mainly for Atmos, so don't want to involve optical any more, so I'm taking HDMI from the Samsung Tv's eArc output to the Beam .
As usual TV apps are no problem, but now I seem to have introduced the audio lag for Sky Q, which no end of adjustment will alleviate.
Is it still a case of putting up with "normal" sound setting from Sky these days? I'm starting to think I shouldn't have bothered with the upgrade..
