+        If <application>pulseaudio</application> was working but you no-longer
+        have sound, after checking for hardware issues (speakers or headphones
+        not connected, external amplifier not connected) you may need to fix it.

+      <para>
+        One suggestion is to close the application, such as
+        <application>firefox</application> where sound has stopped working, then
+        run: <command>pactl list short sinks</command> followed by:
+        <command>pacmd set-default-sink &lt;sink #&gt;</command> and then
+        restart the application.
+      </para>
+
+      <para>
+        If that does not work, a more drastic approach often works. After closing
+        the application, close pulseaudio, either using <command>pulseaudio
+        --kill</command> or, if that fails, <command>killall -KILL
+        pulseaudio</command> and then <command>rm -rf
+        ~/.config/pulse/*</command> (and perhaps also
+        <command>rm -rf ~/.pulse/*</command> if you have used a very old version
+        of pulse on this machine, then run <command>pulseaudio
+        --verbose</command> to restart it. If the daemon starts, restart the
+        application. See <command>man pulseaudio</command> for more options.
