I've just purchased a RX-V3073 (Very similar to the A3020, 9 x 150W. 11.2 capable via pre-out etc) to replace my aging RX-V2700B, but I now notice a lip sync problem.
The audio through the 2700 was perfect, all sources, all resolutions (I had it simply on HDMI pass-through, no processing, no additional audio delay).
But now, the 3073 has a noticeable audio delay/lag by around 1 or 2 frames (I estimate around 60 milliseconds), which is intolerable. I've made sure the delay is set to '0'. I've tried direct video processing, as well as upconversion of all sources to 1080p, but still the persistent audio delay issue.
I even noticed it on audio-only sources, like optical/Toslink from my Apple Airport Express. I was playing the same content through another Airport in another room simultaneously, and the newer Yamaha RX-V3073 had a noticeable delay compared to the audio coming from the other room (Optical from Airport into an even older Yamaha DSP-A1).
Has anyone else had lip sync issues? Why is there so much delay in the audio now on these newer models? Is it all the additional processing on these more complex receivers?
