If, for some reason, you do not hear sound and know that you do have a
sound card installed, you can run 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 configuration screens, use your
[Tab] and [Enter] keys.

| | 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 are 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 does not find any cards, you will be presented with a list
from which you can select your card. Use the [Up Arrow] 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 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.
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
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 |
