SDL audio

does anybody have any experience with the SDL audio part of their multimedia library? I need some help playing a WAV file....I can load the WAV...but not play it.

If you have experience SDL's audio library...tell me what you did to get a WAV file playing.

Here is some of my code:

Code:

#include <SDL.h>
#include <stdlib.h>

int main (int argc, char *argv[])
{
	SDL_Init( SDL_INIT_VIDEO | SDL_INIT_AUDIO );
	SDL_Surface *screen = SDL_SetVideoMode( 640, 480, 32,
		SDL_HWSURFACE | SDL_DOUBLEBUF | SDL_FULLSCREEN );
	atexit(SDL_Quit);
	SDL_EnableKeyRepeat(SDL_DEFAULT_REPEAT_DELAY, 
		SDL_DEFAULT_REPEAT_INTERVAL);

	Uint32 rmask, gmask, bmask, amask;

#if SDL_BYTEORDER == SDL_BIG_ENDIAN
	rmask = 0xff000000;
	gmask = 0x00ff0000;
	bmask = 0x0000ff00;
	amask = 0x000000ff;
#else
	rmask = 0x000000ff;
	gmask = 0x0000ff00;
	bmask = 0x00ff0000;
	amask = 0xff000000;
#endif


	SDL_AudioSpec wav_spec;
	Uint32 wav_length;
	Uint8 *wav_buffer;
	bool opened = true;

	SDL_LoadWAV("shotgun2.wav", &wav_spec, &wav_buffer, 
		&wav_length);	

	SDL_Rect *myRect = new SDL_Rect;
	myRect->x = 100;
	myRect->y = 100;

	SDL_Surface *bmp = SDL_LoadBMP("tile.bmp");
	SDL_Event event;

	while(1)
	{	
		SDL_BlitSurface(bmp, 0, screen, myRect);
		SDL_Flip(screen);
		SDL_FillRect(screen, 0, 0);
		while( SDL_PollEvent ( &event ) )
		{
			switch(event.type)
			{
				case SDL_KEYDOWN:				

					switch(event.key.keysym.sym)
					{
					case SDLK_LCTRL:
						SDL_PauseAudio(0);						
						break;
					case SDLK_DOWN:
						myRect->y += 2;
						break;
					case SDLK_UP:
						myRect->y -= 2;
						break;
					case SDLK_LEFT:
						myRect->x -= 2;
						break;
					case SDLK_RIGHT:
						myRect->x += 2;
						break;
					case SDLK_ESCAPE:
						SDL_FreeWAV(wav_buffer);
						return 0;	
						break;
					}
				break;			
			}
		}
	}
}

Thanx.
