# Gnome Volume Control Manual

## Introduction

&app; (`gnome-volume-control`) is a GNOME enabled audio mixer. &app; allows you to mix audio for 2 channel sound cards.

To run &app; select Multimedia Audio Mixer from the Main Menu, or type `gnome-volume-control` on the command line.

&app; is included in the `gnome-media` package, which is part of the GNOME desktop environment. This document describes version &version; of &app;.

## Using GNOME Volume Control

There are four main components to &app;: the faders, Mute buttons, Rec. buttons, and the Lock buttons. The Lock locks the left and right channels together so that you can adjust either fader and both with be syncronized. The Mute silences the channel, but once you change the volume from the fader the channel is unmuted. The last button, Rec. is toggled to turn on/off the recording functions of your soundcard on that channel. There always has to be one channel with the record button pressed. The faders control the volume of each channel. Below is a listing of what each fader represents.

- Vol — This is the main volume fader.

- Synth — This fader controls the volume of the midi devices.

- Pcm — This fader controls the "wave" files.

- Spkr — This fader controls the Speaker output jack.

- Line — This is the Line input on your sound card, if you have one.

- Mic — This is the Microphone input on your sound card.

- CD — This is the CD player input gain.

- Rec — This is the overall Record level fader. (Master Record level)

- Line2 — If your sound card has a second line input this is the fader that controls the volume.
