I've noticed a few times that audio / video are out of sync on iPlayer in particular (Disney+ doesn't seem to have the issue) and also on Chromecasted NowTV.
This is independent as to whether I'm using the TV to playback the audio or whether I'm putting it through my JVC soundbar.
Should I be configuring a specific delay just for iPlayer (is that actually possible)? And is it just me seeing this?
