It oscillates like that, but take several minutes for a full "cycle". So, setting the audio delay in the Denon isn't helpful. Also, the max delay in the Denon is 200ms, which isn't enough at its worst.
I called Sharp tonight, and the technician was less than helpful. I attempted to walk through the problem as I described it here. But, he cut me off after I said the sync was good when the PC is directly plugged into the TV. He said I have a receiver problem. From that point on, nothing I said would open his mind to other possibilties.
He said that the TV is never the problem. It's always a signal problem. Ok, maybe so...
I explained to him that I simply unplugged the HDMI cable from my Sharp (actively experiencing lip sync problems), and plugged it into another display. The lip sync issues disappeared on the second TV. He said that could be expected because the signal is different. What? So, I repeated myself. He said that HDMI signals are never repeatable, and that my receiver was still the problem. HUH?!
I asked him to explain this, and next he suggested that my problem was that I had too much digital (no kidding). He said that the PC connected to the receiver with HDMI, and the receiver connected to the TV with HDMI = too many digital connections. WTF?!
He suggested I replace some of the connections with component cables, seriously.
He continued on... stating that EVERYONE plugs all
their components into their TV, and use optical or ARC to pass sound to the reciever. I reminded him that this configuration results in loss of HD Audio, and sometimes you only get PCM 2.0, and he still suggested that's what all the pros do! I've never been to a high-end audio store and seen this setup.
I told him I still didn't understand, and he suggested I call back tomorrow and talk to a product specialist. What?!! Who the hell have I been talking to?
I'll call back tomorrow, but I'll test another receiver too.
Oh, he said that I can pass bitstream HD audio through ARC to the receiver. I've never heard of this working, but I'll try it.
