[vlc-devel] [PATCH] lib: Fire event when an audio output is created.

[Mark Lee]

It is no longer possible to get/set the volume for a media player
until *after* an audio output has been created.

This patch adds a new event that will be fired when an audio output
is created.

After this event is received, a call to get/set the media player 
volume will succeed.

This has been implemented in a similar way to that used by the 
existing video output created event.
