Volume controls

The volume controls in section "Output" and "Input" consist of (top to bottom):


Volume control ("Input" Section)
An icon, representing the function of the control.
A Green Mute LED, that allows you to mute a control (light goes off/gets dark) or unmute it again (light goes on/gets bright).
A slider, for volume control (Hint: You can hide the label on the slider, for example if the mixer takes too much of your screen space).
If a control supports recording, there will be a red Record LED. If the LED is lit (bright red), the control is selected for recording. If it is not lit (dark red), the control is NOT selected for recording.

Volume control with Recording Switchi ("Output"Section)

The controls in section "Switches" consist of a LED and a short label describing the function. Please remember, red LED's are for recording issues, yellow LED's are for special soundcard features. If you are uncertain about the meaning of a control, please ask your soundcard driver supplier (for most current Linux distributions this is ALSA from http://www.alsa-project.org).

The volume sliders have a context menu, accessible by right clicking on the slider or device icon (at the top). Several entries are possible, but only those applicable are shown.

Split Channels

Show either one or two sliders. This is only applicable to stereo devices. The right slider controls right side volume, and the left controls left side volume.

Muted

Mute or unmute the device

Hide

If you are not interested in regulating this device you can hide it with this option. If you want to show it again, you can only do this by selecting the Channels option (see below)

Configure Shortcuts

You can control a device with your keyboard. Use this menu option to show the KDE Configure Shortcuts dialog. Here you can define keys for increasing and decreasing volume and for muting the device. The keys are global and operate also when KMix is iconified or docked.

Channels

You will get a dialog box where you can configure per section (Output, Input, Switches), which channels you want to see.

Show Menubar

This option is not device specific, but affects the mixer window. You can hide and show the menu bar with this option. You can also do this by pressing the Shortcut (usually CTRL-m)
