Sound Blaster Audigy problems with Red Hat
Heya,
I have just installed Linux (rank = newbie) and I loaded Red Hat 3.2.3-20 and I am running Linux version (Kernel) 2.4.21-4. ELsmp. At the moment when I run the soundcard detection option within System Settings (using GNOME) it tells me that it detects two sound cards:
1. Intel Corp. 82801EB AC'97 Audio Controller
2. Creative Labs SB Audigy
When I play the test sound for the Audigy card it works fine (most of the time - sometimes no sound plays at all - restarting the Soundcard Detection application usually fixes this) and it does not work for the AC97 card. I'm assuming this is because my speakers are contected to the Audigy output.
I have noticed similar posts for this problem telling me to run the sndconfig command (while logged in as root) and when I do I get the following output:
[root@localhost root]# sndconfig
bash: sndconfig: command not found
The output from the /sbin/lspci command is as follows for my machine:
[root@localhost root]# /sbin/lspci

I assume from this that the two sound devices are conflicting each other however I do not know how to disable one or the other. If someone could please tell me how to do this it would be greatly appreciated. I have also checked the volume levels by running the volume control application from GNOME and running it in a terminal session with the same result.
I have also run the following commands to check the permission levels on /dev/dsp and /dev/mixer and this is the result:
[root@localhost dev]# ls -l /dev/mixer
crw-rw-rw- 1 root root 14, 0 Sep 15 2003 /dev/mixer
[root@localhost dev]# ls -l /dev/dsp
crw-rw-rw- 1 root root 14, 3 Sep 15 2003 /dev/dsp
I'll include the lspci -v command output in case it sheads any more light on the matter.
[root@localhost dev]# lspci -v

Please help me to configure my sound. I would prefer to run the Audigy sound card because that would mean I wouldn't have to unplug my speaker cable everytime I swapped between Windows and Linux. I suspect that the sound is not working (when I play mp3's or CDs) because the two cards are conflicting each other but I don't know how to disable the cards.
Please help me - learning a new OS environment is no fun without a little music!
