+<p>PulseAudio is a networked sound server for Linux and other
Unix like operating systems and Microsoft Windows. It is intended to be an improved drop-in
replacement for the <a
href="http://www.tux.org/~ricdude/apps.html">Enlightened Sound
Daemon</a> (ESOUND). In addition to the features ESOUND provides
-<tt>polypaudio</tt> has:</p>
+PulseAudio has:</p>
<ul>
<li>Extensible plugin architecture (by loading dynamic loadable modules with <tt>dlopen()</tt>)</li>
use of a simple main loop abstraction layer. This allows easy
integration with asynchronous applications using the
<tt>glib</tt>/<tt>gtk</tt> mainloop. Since the asynchronous API

available. A simple main loop implementation is available as well.</p>
<p>The following modules are currently available:</p>
<li><tt>module-combine</tt>: combine multiple sinks into one, adjusting the sample rate if the their clocks deviate.</li>
<li><tt>module-sine</tt>: a sine generate sink input.</li>
<li><tt>module-x11-bell</tt>: play a sample from the sample cache on every X11 bell event.</li>

<p>Version @PACKAGE_VERSION@ is quite usable. It matches and supersedes ESOUND's feature set in nearly all areas.</p>
-<p><b>Warning:</b> polypaudio's client API and protocol are not stable
