#include <iostream>
#include <vector>

#include "define.h"

class CSoundManager {
    private:
        int channel;
        int audio_rate;
        Uint16 audio_format;
        int audio_channels;
        int audio_buffers;

        std::vector<sound> Sound;

    public:
        CSoundManager();

        void  soundBegin();
        void  soundEnd();

        void  loadSound(std::string);
        sound getSound(int);
        void  playSound(int);
        void  removeSound(int);
        void  removeAllSounds();
    };

    Mix_PlayChannel(-1, Sound[_soundId], 0);

#include "CSoundManager.h"

void CSoundManager::soundEnd()
{
    Mix_CloseAudio();
}


In my initialize function I wrote this:
1

// Init
SoundManager.soundBegin();

// load sound
SoundManager.loadSound( "sound/sound1.wav" );


In function onEvent():

case SDL_KEYDOWN:
    switch( ev.key.keysym.sym )
    {
        case SDLK_w:
            SoundManager.playSound(0);
            break;
    }


When I run, and press 'w' key I here just crackle for half a second and then it stops.

Note: In main I declared CSoundManager SoundManager;
"sound" is: typedef Mix_Chunk * sound;

1. Do you know the specific piece of code where the problem is?
2. If it isn't too big of a program could you send it? strongdrinkdev@gmail.com
3. Try SFML, I like it a lot more than SDL and its more modern :D
