Otherwise, it might be wise to return the receiver and wait until they get the bugs out, or check into other models without these problems.
I have not talked to them personally but Onkyo is aware of the problem. If I'm not mistaken, they blamed the PS3. Funny thing is the AVR comes with a little piece of paper that clearly states a sound may be heard from the speakers while playing BR or HD disc and it says this is normal and not a malfunction.

Some are reporting no popping sounds at all, so who knows

It onlt happens with uncompressed PCM, during the initial handshake. Once the signall is locked in, everything is OK. This becomes annoying with BR discs since there are multiple handshakes before the movie starts.
