from icon-naming-utils:

	<icon name="preferences-desktop-sound">
	    <link>gnome-settings-sound</link>
	    <link>knotify</link>
	    <link>xfce4-sound</link>
	</icon>

suitable for mcs panel

	<icon name="multimedia-volume-control">
	    <link>gnome-mixer</link>
	    <link>volume-knob</link>
	    <link>arts</link>
	    <link>kcmsound</link>
	    <link>multimedia</link>
	    <link>xfce4-mixer</link>
	</icon>

suitable for the app itself

would it be possible to change here:

http://svn.xfce.org/svn/xfce/xfce4-mixer/trunk/settings/xfce-mixer-settings.desktop.in

- Icon=xfce4-mixer
+ Icon=xfce4-sound

and in Rodent it'll be just needed a link

xfce4-sound --> xfce4-mixer

if you want to use same icon

Reproducible: Always
