SDL_mixer loop delay

hi!I had worked with SDL_mixer instead of SDL_sound
because the first seem to be easier to use than the
second (you don?t have to implement callbacks) but
when I play the music theme of my game SDL puts a
delay when looping. The friend who wrote the music
worked a lot doing a beautiful loop, but SDL_mixer
destroy it…
also, I don?t know how stopping the sound…
any suggestions??

Is the sound file an MP3 or a WAV or OGG file?
I ask this because in MP3, the exact timing of a file cannot be
determined, causing delays when the song loops. If this is the case, try
using WAV or OGG files
