Well, technically "yes" - and that's what the 1st Sharp support guy said, but...
The fact that the out-of-sync was happening with config #2 gives me reason to be suspicious that this HDMI->rcvr->TV config also might have problems.
Plus, right before I got the 857 I had the Samsumg 75" 9000 Smart/LED TV - using the exact same components - and I had no audio sync problems at all (I exchanged the Samsung for the 857 because of the larger screen size and the price difference).
In addition, all TVs I've had in this home theater configuration worked fine over the years and had no audio sync problems. And the previous TVs were excellent sets from Sony.
I understand that a valid argument could be made that - if you're buying a big screen/high end TV - you (maybe) should have the latest A/V components in place to "handle" it. But, maybe an argument could be made that - if the "video processing" is inducing latency between the video and audio - the manufacturer should increase the clock rate or number of processors involved to decrease said latency.
In any case, the frequency of the out-of-sync audio has decreased with config #1 since this reset I did with the 2nd Sharp person (dunno why this seems to have worked since it's not really a "fix"). As I said, when the problem does occur, I simply change the input of receiver to config #2 and that's been working great.
NOTE: if anyone has any out-of-sync problems to report with the Sharp TVs, please include your configuration and what components you're using.
