Do you think the noise is loud enough that it will damage your speakers?
I'm still wondering if it's the AVR or the BDP. Could be the BDP intermittently corrupts the raw bitstream it sends out, so the AVR can't decode it right or can't detect that its DTD-MA. Some one on another forum about popping noises with DTS-MA had suggested upgrading the HDMI cable to something that could handle higher bitrates. I'm tempted to try that out. I'm currently using a mediabridge/amazon HDMI cable.
I have an LG BD570. I have always run it with bitstream and the issue has only happened infrequently, so I can't speak to whether setting the player to send Multi channel PCM has an impact.
It's hard to say whether the player is the problem, but power cycling the AVR has always fixed the problem for me without doing anything to the player. Like you, I believe it has always been DTS-MA codecs when I have had the problem. Usually at the very beginning of a feature presentation ( following trailers). There is probably some sort of audio format change cue that is being missed, causing the receiver to decode incorrectly, in which case using PCM might be helpful.
As for damage to speakers, it sounds possible, but so far I haven't had damage. Of course, I am quick to grab the volume knob and/ or mute button!
