//| """Support for audio input and output over digital buses
//|
//| The `audiobusio` module contains classes to provide access to audio IO
//| over digital buses. These protocols are used to communicate audio to other
//| chips in the same circuit. It doesn't include audio interconnect protocols
//| such as S/PDIF.
//|
//| All classes change hardware state and should be deinitialized when they
//| are no longer needed. To do so, either call :py:meth:`!deinit` or use a
//| context manager."""
