I only start Audacity from the shortcut at desktop and it begins making crackling noise, as it opens. Any menu I come upon or I close, confirming it, makes a crackle noise, too. All my audacity tracks and projects are full of unexplainable clicks and crackles. I dont know what to do. Anyone help, please. The problem started a couple of weeks ago, as the entire audacity tracks began making strange rumble. I love your program and I cant replace it with another tool.
