'Get the current audio output device identifier.
This complements L{audio_output_device_set}().
@warning: The initial value for the current audio output device identifier
may not be set or may be some unknown value. A LibVLC application should
compare this value against the known device identifiers (e.g. those that
were previously retrieved by a call to L{audio_output_device_enum} or
L{audio_output_device_list_get}) to find the current audio output device.
It is possible that the selected audio output device changes (an external
change) without a call to L{audio_output_device_set}. That may make this
method unsuitable to use if a LibVLC application is attempting to track
dynamic audio device changes as they happen.
@return: the current audio output device identifier None if no device is selected or in case of error (the result must be released with free() or L{free}()).
@version: LibVLC 3.0.0 or later.'
