How to call it:
SoundNameis thenamewe have given the sound we want to playChildis theChildTypethat we want to call this method on
string soundName = "SoundName";
ChildType child = ChildType.PARENT;
AudioError err = am.Play(soundName, child);
if (err != AudioError.OK) {
    Debug.Log("Playing sound called: " + soundName + " failed with error id: " + err);
}
else {
    Debug.Log("Playing 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.Play(soundName);
if (err != AudioError.OK) {
    Debug.Log("Playing sound called: " + soundName + " failed with error id: " + err);
}
else {
    Debug.Log("Playing sound called: " + soundName + " succesfull");
}
When to use it: When you want to play a sound directly without changing its initally properties.
Remarks: If you want to enable looping for a sound (see Adding a new sound) for more information. See AudioSource.Play for more details on what play does.
