Moblin Applets: Volume

Snapshot

Overview

This status bar applet simply controls the volume of the primary sound element. The pse is determined by libvolumecontrol as it scans the available track names for keywords like "master" and "Speaker". If it doesn't find any matching tracks it simply assumes the pse is the first playback track with both volume and mute capability.
