RE: Dell Inspiron 11 (3147, Mid 2014) makes crackling sound whenever sound is played
On my laptop I prevent automatic updates of drivers. Open Windows Update (type that into the Windows search box), then click on Change settings. In the dropdown menu select "check for updates but let me choose..." Then Windows will notify you when updates are available for downloading. Always allow the ones labelled "important", which will be security patches and such, but be selective about the ones labelled "optional", which will be driver updates and things like that.
