10.3.1. If Sound Card Configuration Tool Does Not Work
If the Sound Card Configuration Tool 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 the
Sound Card Configuration Tool. You can edit your
section (this strategy is not recommended for most new users) or refer to the documentation that came
with your sound card for more information.
10.3.1.1. Manual Sound Card Configuration
If your sound card is not a plug and play card, you can manually edit your
to include the sound card module that it should use. You must have root privileges to alter this file.
The following is an example of the text to add to your
alias sound sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=7 dma=0,1 mpu_io=0x300
For information on configuring sound manually, refer to the Linux Sound HOWTO at the Linux Doc-
umentation Project webpage:

10.4. Troubleshooting Your Video Card

Video card configuration is handled during the Red Hat Enterprise Linux installation (refer to the Red
Hat Linux Installation Guide for more information). However, if you did not choose to configure a
video card at that time, or if you need to reconfigure your settings, you can use the X Configuration
Tool utility. Use this utility if you install a new video card.
Note
The X Configuration Tool backs up your system's original video configuration file to
/etc/X11/XF86Config.backup

in case you need it to switch back to a previous configuration.
