    Play the source to completion.

    `source`: `Sound` - The microbit module contains a list of built-in sounds that your can pass to
    audio.play(). The source agrument can also be an iterable of AudioFrame elements as described below.

    If `wait` is True, this function will block until the source is exhausted.

    `pin` An optional argument to specify the output pin can be used to override the default of
    pin0. If we do not want any sound to play we can use pin=None.

    `return_pin`: specifies a differential edge connector pin to connect to an external speaker
    instead of ground. This is ignored for the V2 revision.
