void aout_OutputDelete ( audio_output_t * aout )

Stops the audio output stream (undoes aout_OutputNew()).

Note: This can only be called after a succesful aout_OutputNew().

Warning: The caller must hold the audio output lock.

Parameters

wait	if true, wait for buffer playback (i.e. drain), if false, discard the buffers immediately (i.e. flush)

Note: This can only be called after a succesful aout_OutputNew().
