10.3. Troubleshooting Your Sound Card
If, for some reason, you do not hear sound and know that you do have a
sound card installed, you can run the Sound Card Configuration Tool
utility.
To use the Sound Card Configuration Tool, choose
=> => . A small text box pops up prompting you for your
root password.
 | Note |

| | Most sound cards are supported by Red Hat Linux, but
there are some sound cards that are not completely compatible or may not
work at all. If you are having trouble configuring your sound card,
check the Hardware Compatibility List at https://hardware.redhat.com/ to
see if your card is supported. |
The Sound Card Configuration Tool utility probes
your system for sound cards. If the utility detects a plug and play sound
card, it will automatically try to configure the correct settings for your
card. You can then click the Play test sound button
to play a sound sample. If you can hear the sample, select
OK and your sound card
configuration is complete.
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
modules.conf file as discussed below (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 /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 |
For information on configuring sound manually, refer to the
Linux Sound HOWTO at the Linux Documentation
