I just bought a Dell Dimension 9100 and after I have installed Fedora Core 4 it does not detect my sound card. Does anyone have any ideas of what I can do or what driver would work.

The sound card is a Sound Blaster Audigy..

Welcome to LQ. Are you sure that the system is not detecting the sound card, or could it just be that the volume is muted, or that there's some sort of physical problem (ie, the card is installed but the speaker cable isn't plugged in). Can you post the results of running these two commands
The first command will list the PCI devices that are recognized, and the second will list the kernel modules that are installed. -- J.W.

Here is the lsmod output:

I also got this message after rebooting...

Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (Invalid argument)
The sound server will continue, using the null output device.

What are the permissions on /dev/dsp and /dev/mixer? They should be at least 666 -- J.W.

I changed the permissions for both to 666.

Still no sound..

Also I still get this message at boot up..
