Is there a function that can play mp3 files? Or maybe a good tutorial?

a) MP3s have absolutly no connection with OpenGL. (hint hint. GL=Graphic Library)
b) This have been asked number of times before. Next time spend 5 minutes searching before posting.
c) There are number of other librarys that you can use for this: BASS, FMOD, OpenAL,...

OpenGL is a graphics library and as such has no built-in functionality to play sounds. OpenAL, FMOD, BASS, and DirectSound are all audio libraries that you might want to look at. I don't have any links on me at the moment, but the search on the articles page should turn up some good results. I'm pretty sure that GDNet hosts a few articles for each of these libraries so it shouldn't be hard to find.

Playing audio has nothing to do with OpenGL. OpenGL is a graphics library.

Instead, search for resources on OpenAL or Fmod, and try the articles section on this site.

Yes the "official" search is down, but like I said the google search in the articles section is working perfectly. It even finds a good number of the related posts in the forums.

This page can be found in the articles section. Specifically, you might want to check out the Music and Sound articles.

Or go to the Articles page, and use the searchforum.
