[openal] My code runs with no errors, but no sound

[Patrick Baggett]

You can also reduce the test case to "can I hear anything or not" by
filling a buffer with white noise instead of trying a WAV file if you think
the file loader is the problem:

const ALsizei freq = 44100; //samples / sec
const ALsizei noise_size = freq * sizeof(int16_t) ; // 1 second * 44100
samples / second  * 2 bytes  / sample = 88200 bytes

//Generate white noise
srand(time(NULL));
int16_t* noise = malloc(noise_size);
for(int i=0; i<freq; i++) {
     noise[i] = (int16_t)(rand() & 0xFFFF);
}

alBufferData(source[0], AL_FORMAT_MONO16, noise, noise_size, freq);
