<p>
autoaudiosrc is an audio source that automatically detects an appropriate
audio source to use. It does so by scanning the registry for all elements
that have <span class="quote">“<span class="quote">Source</span>”</span> and <span class="quote">“<span class="quote">Audio</span>”</span> in the class field
of their element information, and also have a non-zero autoplugging rank.
