I am unable to use Airplay cast to my home system when casting to my Sony HT-A7000 soundbar using line-in to my WiiM Pro because of severe sync latency problems which cannot be resolved with either auto or manual audio sync. I have logged a ticket but wondered whether other users have experienced similar problems? Is it an issue with a digital processing delay within the Sony soundbar perhaps? (As it’s not an AVR I don’t have any Pure Direct facility).
