Mine does the same thing, always has, i dont think its anythign to worry about. I turned my speaker all the way down and it still makes the sound....Im not so sure its that.
It doesn't matter if you turn the speakers all the way down, I suspect the popping is caused during initialization of the audio curcuit of the nook. As there is no physical volume control "turning it down" doesn't help. Most computers have a subtle "pop" you can hear in the speakers when you turn them on and their audio cards come online.
This makes sense, and it would affect battery life. It should not be initializing the audio circuit randomly when it's supposed to be asleep, but if it is, then that would make the battery life less. And honestly, the noise wakes me up. I'm a light sleeper and don't want to have to take the nook out of the room before going to sleep since I use reading to fall asleep.
Do the tech people ever read these messages?
