Your sound card should be identified and configured during the NLD installation. The audio functionality is provided by Advanced Linux Sound Architecture (ALSA), which is licensed under GNU.
ALSA supports most sound cards. However, some new sound cards or even existing sound cards (from more obscure vendors) may not be supported. You can attempt to fine-tune the settings for an unsupported card and manually choose the driver for the card. In terms of supporting new hardware, sound cards included, it is important that you update your NLD system using Red Carpet whenever the Updates Available notification icon appears in the top panel of the desktop.
When you boot NLD, sound on your NLD system is initiated by the sound server. As a user, you can enable system sound events and select the sounds for specific events. Of course, you also have control over the sound volume and settings for specific devices such as a microphone, the CD drive, and video sound.
Advanced sound settings related to adding or configuring a sound card can be accessed via the Administrator Settings (select Hardware and then Sound), but you need to know the root password to perform actions in YaST. Because the sound card is set up at installation, the use of YaST to configure the sound card will probably require little attention from you.
Open Sound Preferences
Set Sound Events
The sound files used by the NLD events are in the .wav format. You can search the Web and download any number of .wav files and assign them to events to personalize your NLD system. Your sound scheme can actually be matched to the desktop background and the theme that you assign to NLD.
Enable System Bell
Set Volume Level
Open Volume Control
Set Volume Control
The appearance of the Volume Control dialog box and the settings available depend on the capabilities of the sound card that you have installed on your PC.
