/** A simple base class for audio sinks.
* This is the most simple base class for audio sinks that only requires
* subclasses to implement a set of simple virtual functions:
*
* - open_vfunc() - Open the device.
* - prepare_vfunc() - Configure the device with the specified format.
* - write_vfunc() - Write samples to the device.
* - reset_vfunc() - Unblock writes and flush the device.
* - get_delay_vfunc() - Get the number of samples written but not yet played
* by the device.
* - unprepare_vfunc() - Undo operations done by prepare.
* - close_vfunc() - Close the device.
*
* All scheduling of samples and timestamps is done in this base class together
* with Gst::AudioBaseSink using a default implementation of a
* Gst::AudioRingBuffer that uses threads.
