Mix_PlayMusic indefinite looping

SDL Development
1

Let’s say I only want to play music once, according to the reference documentation I would write this: Mix_PlayMusic(music, 1). But for some reason it plays my music in an endless loop. Even when I set loops to 0 like this: Mix_PlayMusic(music, 0) I get the same result. I don’t have this problem when using Mix_Chunk with Mix_PlayChannel, everything works as advertised.

This is my test code for Mix_PlayMusic:

#include "SDL.h"
#include "SDL_mixer.h"

int main(){
SDL_Window *window = NULL;
SDL_Renderer *renderer = NULL;
SDL_Event event = {0};
SDL_bool is_running = SDL_TRUE;
Mix_Music *music = NULL;

SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO);
Mix_Init(MIX_INIT_MP3|MIX_INIT_OGG);
Mix_OpenAudio(MIX_DEFAULT_FREQUENCY, MIX_DEFAULT_FORMAT, 2, 1024);

SDL_CreateWindowAndRenderer(816, 640, SDL_WINDOW_SHOWN, &window,&renderer);

music = Mix_LoadMUS("Battle1.ogg");
Mix_VolumeMusic(30);
// Still plays music in an infinite loop, despite loop being set to 0 here...
Mix_PlayMusic(music, 0);

while(is_running){
  while(SDL_PollEvent(&event)){
    switch(event.type){
      case SDL_QUIT:
        is_running = SDL_FALSE;
        break;
    }
}

  SDL_RenderClear(renderer);
  SDL_RenderPresent(renderer);
}

  Mix_FreeMusic(music);
  Mix_CloseAudio();
  SDL_DestroyRenderer(renderer);
  SDL_DestroyWindow(window);
  Mix_Quit();
  SDL_Quit();
  return 0;
}

This is my test code for Mix_PlayChannel:

#include "SDL.h"
#include "SDL_mixer.h"

int main(){
  SDL_Window *window = NULL;
  SDL_Renderer *renderer = NULL;
  SDL_Event event = {0};
  SDL_bool is_running = SDL_TRUE;
  Mix_Chunk *chunk = NULL;

  SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO);
  Mix_Init(MIX_INIT_MP3|MIX_INIT_OGG);
  Mix_OpenAudio(MIX_DEFAULT_FREQUENCY, MIX_DEFAULT_FORMAT, 2, 1024);

  SDL_CreateWindowAndRenderer(816, 640, SDL_WINDOW_SHOWN, &window,&renderer);

  chunk = Mix_LoadWAV("Computer.ogg");
  Mix_Volume(-1, 30);
  Mix_PlayChannel(-1, chunk, 1);

  while(is_running){
    while(SDL_PollEvent(&event)){
      switch(event.type){
      case SDL_QUIT:
        is_running = SDL_FALSE;
        break;
      }
  }

  SDL_RenderClear(renderer);
  SDL_RenderPresent(renderer);
}

  Mix_FreeChunk(chunk);
  SDL_DestroyRenderer(renderer);
  SDL_DestroyWindow(window);
  Mix_CloseAudio();
  Mix_Quit();
  SDL_Quit();
  return 0;
}
