Cannot play Audio file but can load

Game Development
1

So from yesterday i am trying to play audio with this and it does not play:
//Opening according to web and youtube
Mix_OpenAudio(44100,MIX_DEFAULT_FORMAT,2,1024);

//Audio file
Mix_Music* Hudba = Mix_LoadMUS(“Audio/Garage-theme.mp3”);
//Error check
if (!Hudba)
{
std::cout << “Chyba:” << Mix_GetError(); return 1;
}
//Playing
Mix_PlayMusic(Hudba, 1);

Wav and mp3 are loading and found but not played. Do you know how to play them in c++? Do i have to play music in game loop or outside of game loop?

and also sorry if question sounds weird because its my first question on sdl

Did you call:

SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO)

This is good practice in general, but Mix_OpenAudio() will call SDL_Init() for you if you forgot, so that’s not the problem in this case.

It’s not clear from the original post, but assuming there’s no loop in there, the @pavel5750cz might be thinking that Mix_PlayMusic blocks until the song completes; it does not, and the app needs to continue until the song is done playing.

If the program ends right after the call to Mix_PlayMusic, it won’t play anything.

I have loop inthere. And from what i understood is that i have to play kt outside. This is my first post so sorry for not enough info . Because of this i wanted to leabe sdl and switch to open gl

You should be able to start the music from anywhere in your program (assuming you have initialized SDL first).

OpenGL is a graphics API and has nothing to do with audio.
There is nothing preventing you from using OpenGL with SDL.

Also note that you should not free the Mix_Music object using Mix_FreeMusic until after you have finished playing the music otherwise it will stop the music.

i have it outside of loop and it looks like that and does not play :Mix_OpenAudio(44100, MIX_DEFAULT_FORMAT, 2, 1024);

Mix_Music* Hudba = Mix_LoadMUS("Audio/Garage-theme.mp3");
if (!Hudba)
{
	std::cout << "Chyba:" << Mix_GetError(); return 1;
}

Mix_PlayMusic(Hudba, 1);

So the program keeps running but without playing any music?

It would help if you posted a complete example program, with everything that is not relevant removed, but that can still be compiled and run to show the problem.
