[. . . ] You can find information about these settings in your sound card documentation. If you share your machine with Windows, you can also find your sound card's settings in the Device Manager tab, in the System section of your Control panel. Once you have selected the right settings for your card, you will be presented with sound samples. If you hear the samples, select Ok and sound configuration is complete. After your card is configured, type exit. You will be returned to your user account. 8. 1. 1 If sndconfig Does Not Work If sndconfig does not work (if the sample does not play and you still do not have audio sounds), there are alternatives, although they are not quite as simple as running sndconfig. You can edit your 102 Chapter 8:Audio, Video, and General Amusement modules. conf file as discussed below (this strategy is not recommended for novices), or refer to the documentation that came with your soundcard for more information. If your soundcard is not a plug and play card, you can manually edit your /etc/modules. conf file to include the sound card module that it should use, for example: alias sound sb alias midi opl3 options opl3 io=0x388 options sb io=0x220 irq=7 dma=0, 1 mpu_io=0x300 8. 2 Speakers, Headphones, and Sound Etiquette Most computers have a plug on the back of the CPU designated for speakers and headphones. If you have configured your sound card, any system or website sounds should play through the speakers or headphones. Your CD-ROM probably has a plug near it as well, so you can listen to music CDs through the CD-ROM drive. Regardless of how you choose to listen to music or other sounds, you should remember that there may be other people working near you who are not interested in hearing your computer. Even headphones can "bleed" noise and disturb others. Add the Mixer Applet (Main Menu => Panel => Add to Panel => Applet => Multimedia => Mixer) to your panel so you can control system volume. Click on the speaker icon in this applet to mute or activate sound and use the slider bar to control volume level. Note that the CD-ROM probably has its own volume control next to the CD drawer on your computer. 8. 3 Playing CDs You should be able to put a music CD in your CD-ROM and see the CD player start automatically. If not, in GNOME, go to Main Menu => Programs => Multimedia => CD player to open the CD player. In KDE, go to Main Menu => Multimedia => CD Player. Section 8. 4:Configuring a Video Card 103 Figure 8­1 GNOME CD Player Interface The CD player interface acts like a standard CD player, with play, pause, and stop functions. A volume control slider is located at the bottom of the interface. You can also edit the track listings for your CDs and change the way the utility functions by clicking on the Open Track Editor and Preferences buttons and making your selections. Set your preferences to use CDDB and it will look up the name of the CD and its songs from an extensive online database and list them in the GUI. The first time you play a CD, you will need to be online for this feature to work; the information will be stored and displayed in the future whether you are online or not. This is not a requirement -- it is just a convenient feature. 8. 4 Configuring a Video Card You probably configured your video card during installation (see the Official Red Hat Linux Installation Guide), but you can change your video configuration settings at any time using the Xconfigurator utility.
