RE: Dell Inspiron 11 (3147, Mid 2014) makes crackling sound whenever sound is played

I think I have figured out this issue on my computer by sear luck! Click on the battery icon in the bottom right and then turn off Power Saver mode. That seems to have taken away the crackling noise. My guess is that Power Saver lowers the processing power so it's not enough to handle video properly. Regardless of what it is, it worked for me.
