Is this what's responsible for loud pops when I stop playing music for a
couple of seconds, or restart after not using it?
I use headphones in a multi-use audio jack port on a Dell desktop machine.
And they pop quite loudly every time I start playing audio again after a little
while, or when I stop/pause for more than a couple of seconds.
