2.14 Controlling Sound
YaST automatically identifies and configures the sound cards in your computer. You
can also use the YaST Hardware module to configure your sound card manually. When
your sound card has been configured, you can control the volume and balance of the
sound with the GNOME Volume Control mixer.
GNOME uses the PulseAudio sound server by default. PulseAudio allows to control
audio “streams” of different programs with one GUI. This makes it able to, for example,
use two different programs generating audio output at the same time by sending their
output to different devices such as headphones and speakers.
If the mixer icon (a loudspeaker symbol) is not visible in the panel on your desktop,
press
Alt + F2 and enter
gnome-volume-control
, or click Computer > More Ap-
plications > Multimedia > Volume Control.
Left-click on the mixer icon and move the slider up or down to change the overall vol-
ume. Right-click and choose Open Volume Control for a detailed configuration dialog.

Playback
Shows all playback streams currently active. You may adjust the volume of a stream
or mute it. Right-click on a stream to either terminate it or to move it to another
sound device (if available).
