Stop
What it does: Stops the sound if it is currently playing and returns an AudioError (see Possible Errors), showing wheter and how stopping the sound failed.
- DOES_NOT_EXIST
 - MISSING_WRAPPER
 - MISSING_SOURCE
 - MISSING_CLIP
 
How to call it:
SoundNameis thenamewe have given the sound we want to stopChildis theChildTypethat we want to call this method on
string soundName = "SoundName";
ChildType child = ChildType.PARENT;
AudioError err = am.Stop(soundName, child);
if (err != AudioError.OK) {
    Debug.Log("Stopping sound called: " + soundName + " failed with error id: " + err);
}
else {
    Debug.Log("Stopping sound called: " + soundName + " succesfull");
}
Alternatively you can call the methods with less paramters as some of them have default arguments.
string soundName = "SoundName";
AudioError err = am.Stop(soundName);
if (err != AudioError.OK) {
    Debug.Log("Stopping sound called: " + soundName + " failed with error id: " + err);
}
else {
    Debug.Log("Stopping sound called: " + soundName + " succesfull");
}
When to use it: When you want to stop the given sound, if you restart it later the sound will start anew. So to really only pause it use the Toggle Pause method.
Remarks: See AudioSource.Stop for more details on what stop does.
