<h1>ao_default_driver_id</h1>
<p><i>declared in "ao/ao.h";</i></p>
<p>Returns the ID number of the default live output driver.
If the <a href="ao_conf.html">configuration files</a> specify a
default driver, its ID is returned, otherwise the library tries to
pick a live output driver that will work on the host platform.
