   <li><p><b>I often hear noises when playing back with Polypaudio, what can I do?</b></p>
   <p>There are to possible solutions: either make the polypaudio
   binary SUID root (<tt>chmod u+s /usr/bin/polypaudio</tt>) and run it
-  with argument <tt>-r</tt> or increase the fragment sizes of the audio
+  with argument <tt>--high-priority=1</tt> or increase the fragment sizes of the audio
   drivers. The former will allow Polypaudio to activate
   <tt>SCHED_FIFO</tt> high priority scheduling (root rights are dropped
-  immediately after this).</p></li>
+  immediately after this) Keep in mind that is a potential security hole!</p></li>
 
+  <li><p><b>I only want to run polypaudio when it is needed, how do I do this?</b></p>
