Sound capability is included, but is not configured to run
automatically when you install Red Hat Linux. If you want to hear sound, you'll
need to configure your sound card with the
sndconfig utility.
To use sndconfig:
From a shell prompt, use the su - command to
become root.
Type sndconfig
at the command line.
To navigate through the Yes,
No, Cancel, and option buttons, use your [Tab] and
[Enter] keys.
 | Is Your Sound Card Supported? |
|---|
| | Many sound cards are supported for Red Hat Linux, but there are sound cards
that are not completely compatible, or even compatible at all. If
you're having trouble configuring your sound card, check the Hardware
Compatibility List at http://hardware.redhat.com/
to see if your card is supported.

The sndconfig 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 by playing sound
samples. If you can hear the samples, just select
Ok when instructed and your sound card
configuration is complete.
If the probe doesn't find any cards, you'll be presented with a list
from which you can pick your card. Use the up and down arrow keys to
scroll through the list. If your card is listed, highlight it, then
press [Enter] (or [Tab] to the
Ok button and press [Enter]).
Your next task will be to select the correct I/O port, IRQ, and DMA
settings. These settings are determined by the jumper settings of the
sound card. 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've selected the right settings for your card, you'll 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.
If sndconfig doesn't work (if the sample
doesn't play and you still don't have audio sounds), there are
alternatives, although they're not quite as simple as running
sndconfig. You can edit your
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 |
