4.1 Cambridge Soundworks Surround sound on my computer, for listening to music.

And then crepe Labtec PC speakers that I use on my TV because it has a horrible internal speaker that's squashed onto the side of it and gives terrible sound, the speakers aren't that bad, but give crackle and hiss at high volumes, unlike my PC speakers.

I think, if I had more money, I'd spend it on a better TV before I got a decent sound system.
