I run Mint as the OS on my main computer at home. For the most part it gives me no trouble, I can do everything I need to do on it far quicker and reliably than I ever could on a windows machine. Between growing Linux support for software natively and Wine I dont ever see a need to return to Windows.
However every once in a while I will get crazy distortion randomly popping up. I could be watching a YouTube video or playing a game and the sounds will become incredibly crackily and distorted. I finally found a fix though.
Open up a terminal session and just type
pulseaudio -k. That will kill the sound daemon. Restart it with
pulseaudio --start. After that your sound should return to normal.
