ETA: I can't listen to music at work.

It says "No Audio Device" on our computers. Funny thing is at my old job, we didn't have games (like solitaire and minesweep) but we could listen to music on our computers. Now at this job, we have the games but no sound. I keep saying I need to buy a new mp3 player so I can listen to music at work...might wait until after the new year to see if there's any after Christmas deals.
