Popping when playing multiple sounds

[zoul]

Same problem experienced by pwightman:

I'm essentially using Finch as a sampler of sorts for when users press notes, it plays the sample I've recorded
corresponding to that note. But every time I call "Stop" on the sound, I get a small but noticeable popping sound. It
happens sometimes when multiple sounds are played at once when the sound begins, but always happens when you
release the sound. Any idea why it might be? I'm not necessarily sure if it has much to do with your code, but I've
searched and searched for why this might be happening and can't find anything that fixes it anywhere.

I have a hacky fix. I found that the pop occurs when alSourceStop(source) occurs. Pausing the sound does not cause a pop but you must pause the sound before the sound ends naturally and call the play function again to get the sound to the rest.

so I have

- (void) rewind 
{
    CLEAR_ERROR_FLAG;
    alSourcePlay (source);
    alSourcePause(source);
    // [self performSelector:@selector(rewind2) withObject:self afterDelay:1.1];
}

- (void) play
{
    // if (self.playing)
    // [self stop];
    CLEAR_ERROR_FLAG;
    alSourcePlay(source);
    [self checkSuccessOrLog:@"Failed to start sound"];
}

and when I stop the sound now I call.

sitar.gain=0.01;
[self rewind];

This plays the sound from the start and pauses it instantly. When I play the sound again there are no pops.

Nick, thanks for the info! I’ll leave the issue open until it’s fixed here on GitHub. (Not sure when I’ll have the time yet.)
