<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.

<h3>Return Values</h3>
<blockquote>
<li>a non-negative value is the ID number of the default driver.</li>
<li>-1 indicates failure to find a usable audio output device.</li>
</blockquote>
<p>
<h3>Notes</h3>
<p>If no default device is available, you may still use the null device
to test your application.</p>
