Testing the Sound Card
To test the sound driver, you should try playing a sound file. A good way to do this is to insert an audio CD-ROM into your CD-ROM drive, and play a sound track. See the section “Playing Audio CD-ROMSs” for more information about various CD Player applications.
If you don’t have an audio CD-ROM handy, you can use the X Multimedia System (XMMS) to open and play a sound file. XMMS can play many types of sound files, including MP3 and Windows WAV. You will find many WAV sound files—which usually have names that end with the .wav extension—in the /usr/share/sounds directory of your Red Hat Linux system.
