rsp-2572 hdmi audio delay

[sickmint79]

i've seen this issue but am unclear on any resolution?

if i just play through videos on youtube it seems the first second or so is skipped, like the system is determining what kind of algo to process the audio. how can this be on such a pricey preprocessor? in all cases so far i've noticed this same behavior, starting a movie or show or video.

i'm now, in my first and only case, observing it actually happening in and out on a show. i'm watching the first episode of season 21 south park on a roku through the hulu app. there are specific parts where audio is dropped even mid dialogue, and they drop if i rewind and replay the scene as well. what's going on here and is there a way to fix it?

I had Rotel RSX-1550, RSP-1570 and now RSP-1572 and all of them has this delay. Between theses, i had Denon, Yamaha receivers which worked flawless. But they doesn't had the Rotel sound quality. So i decided to stay on Rotel even with this annoying issues.
Using optical cable reduces but doesn't eliminate these effects.
