The Xfce panel plugin presents itself with a nice speaker icon. Clicking onto the icon, volume can be changed:
xfce4-mixer Speaker Icon |
---|
There's also the well-known context menu, providing muting functionality, running the mixer application or opening the properties dialog:
xfce4-mixer ContextMmenu |
---|
For the plugin and volume settings to work, you have to have the correct sound card and channel selected in the plugin's properties dialog:
xfce4-mixer Sound Card and Channel Dialog |
---|
In addition, it provides a simple-to-use mixer application. Of course, everything is fully translated into many different languages:
xfce4-mixer Application |

The mixer works smoothly not only with the well-known ALSA setup, but also with PulseAudio:

The panel plugin optionally supports global keyboard shortcuts for raising and lowering the volume, as well as muting the selected track if compiled against libkeybinder. The plugin will then handle the XF86AudioRaiseVolume, XF86AudioLowerVolume, and XF86AudioMute keyboard symbols.
The mixer application supports the following properties in the xfce4-mixer channel:
/window-width
width of the main window (integer)/window-height
height of the main window width (integer)/sound-card
