Xfce4 - uninstalled pulseaudio - no volume control for alsa for the panel

[Aldo Maggi <sentiniate@virgilio.it>]

As for the Subject, I' ve uninstalled pulseaudio because after an
upgrade I couldn't hear anything from the speakers (it happened already
in the past more than once).

Now I have audio again but it appears that there is no plugin for alsa
to use in the lower panel.

I've installed "volti", it works but I cannot have it in the lower
panel.

Aldo :-)
