//| """Support for audio output
//|
//| The `audioio` module contains classes to provide access to audio IO.
//|
//| All classes change hardware state and should be deinitialized when they
//| are no longer needed if the program continues after use. To do so, either
//| call :py:meth:`!deinit` or use a context manager. See
//| :ref:`lifetime-and-contextmanagers` for more info.
//|
//| For more information on working with this module, refer to the
//| `CircuitPython Essentials Learn Guide
//| <https://learn.adafruit.com/circuitpython-essentials/circuitpython-audio-out>`_.
//|
//| Since CircuitPython 5, `RawSample` and `WaveFile` are moved
//| to :mod:`audiocore`, and `Mixer` is moved to :mod:`audiomixer`.
//|
//| For compatibility with CircuitPython 4.x, some builds allow the items in
//| `audiocore` to be imported from `audioio`.  This will be removed for all
//| boards in a future build of CircuitPython."""
