Is there a USB device to play a sound on a mac?
I'm looking for a USB-type device (or possibly line-in?) to play a sound on my mac. The purpose would be that I listen to loud music and zone out everything around me while I'm programming, so if someone could push a buzzer. I'm aware there are other ways to get my attention, but I'm looking for something more techie ;) Kind of like the staples "That was easy" button, but to play the sound through my computer rather its own speakers.
