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. It is then, for example, possible to use two different programs generating audio output at the same time by sending their output to different devices such as headphones and speakers.
