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

02:0d.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)
02:0d.1 Input device controller: Creative Labs SB Audigy MIDI/Game port (rev 03)

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.

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!

try lsmod and see if you have any modules loaded that look like they are for your intel sound thing. Then try rmmod (might crash your computer, but what the hey) and see if it will remove it. If you recompile your kernel (kind of a big project if you just got started) you can make sure you don't include the intel drivers and just the audigy ones. I've had two sound cards on my other desktop when I had linux on it (audigy and realtek) and I haven't had a problem with it.

Thanks for your reply! Regarding lsmod, this is the output I get:

[root@localhost dev]# lsmod
Module Size Used by Not tainted
i810_audio 28936 0 (unused)
audigy 83872 0 (unused)
sound 77676 0 [audigy]
ac97_codec 16104 0 [i810_audio audigy]
soundcore 7044 9 [i810_audio audigy sound]

I ran the rmmod command for the i810_audio module and this was the output I received:

[root@localhost dev]# rmmod -v i810_audio
Checking i810_audio for persistent data
rmmod: module i810_audio is not loaded

However when I ran lsmod again it showed the module had been removed from the list. The AC97 is still visible when I run Soundcard Detection though. And removing that module did not change the audigy module into the used state.

ie:
[root@localhost root]# lsmod
Module Size Used by Not tainted
audigy 83872 0 (unused)
sound 77676 0 [audigy]
ac97_codec 16104 0 [audigy]
soundcore 7044 7 [audigy sound]

Any other thoughts on this matter, not sure I'll be good at reconfiguring the kernel.

After you do an rmmod on the intel driver, did it help with the problem at all?

I also forgot, you might be able to turn off onboard sound with some switch on your motherboard, so also check that out.
