The GNOME Volume Control window contains the following elements:

Menubar

  The menus on the menubar contain all of the commands that you need to work with GNOME Volume Control.

Display area

  The display area contains the channel faders and associated options for several mixers, which enable you to control the volume on those mixers.

  GNOME Volume Control populates the display area dynamically, based on the functionality supported by your sound card. The mixers displayed in your GNOME Volume Control window might be different to those shown in Figure 1.

## Usage

### To Change a Mixer Volume

To change a mixer volume, use the channel faders for that mixer, as follows:

- To increase the volume, slide the fader up.

- To decrease the volume, slide the fader down.

### To Lock the Mixer Channels

To lock the left and right mixer channels together, select the Lock option for that mixer. When you lock the mixer channels, GNOME Volume Control synchronises both faders.

### To Silence a Mixer

To silence a mixer, select the Mute option for that mixer.

When you adjust the fader of a muted channel, GNOME Volume Control deselects the Mute option for that mixer.

### To Specify the Current Recording Source

Any mixer that has a Rec option can be a recording source.

To specify the current recording source, select the Rec option for that mixer.

## Preferences
