USB Sound Card
The mini-jack audio connector on the front of my PC has a lot of noice on it, totally useless, and I need a second audio output for my headphones. I could just swap the connection on the mini-jack on the back of the computer each time I want to connect my headphones, but that is a bit annoying. So I decided to make my own USB sound card instead.
