Using sound in C?

[TeamEvolution]

Yea I downloaded mikmodlib and madlib to see if I can play sounds and I'm still searching for this answer but what is the line or w/e i have to do in order to play some sound at least. Mostly I'd like to play MP3s and WAVs. If you do know please tell me... I use the pspsdk and cygwin with it. And also how do I show images? I got libpng and i think something else i forgot installed... HELP PLEASE AND THANK YOU!!!
