Just so people are 100% clear on this issues... it is NOT software related in any way. You can unplug the unit from the wall and wait days and it will still pop and snap. No software update will ever fix this physical issue.
The sounds it makes is from the plastic expanding and contracting from either external temperatures or from when you use it and it warms up.
Again it is also worth mentioning that I started with MK1 with this issue. I then replaced it with TWO separate MK2 over the course of a couple years. No luck.
B&O support was totally useless every time I brought it up to them. They kept making stupid suggestions as "try a different Wifi channel" or "connect it with ethernet" even though I made it clear it was still popping when playing no music and its not even plugged into power.
B&0 actually took my unit twice for weeks and called me back "Its working perfectly with no problems" only to take it home and have it pop within minutes of coming back home.
Shame, such a nice product with one ridiculous hardware flaw. The saddest part is B&O still seems like they aren't even aware of it.
I hope loosening the screws helps though.
