Once VolWheel has been launched, the volume can be adjusted up or down by placing your cursor over the tray icon and using the scroll wheel of your mouse or touchpad. To mute, simply middle-click on the icon.

From the preferences window, accessible by a right-click menu, you can select the default audio channel, such as Master or PCM, as well as the default mixer command which is executed when you left-click on the tray icon.

By default, VolWheel uses the standard GNOME volume control icon (pictured above), however this can be customized to whatever you want by simply altering the icon’s file path in the source script.

VolWheel is written in Perl and currently depends on the following packages:

• gtk2-perl
• perl-gtk2-trayicon
• alsa-utils
• gnome-icon-theme
