well, You should have to follow steps gicen below to setting up ALSA drivers on RH 9.0
1. This receipe discusses the steps that I took to install the ALSA drivers on my RedHat 9.0 Linux System. The documentation that is provided on the ALSA website is not enough, in my opinion, and a few things need to be done before you can sail safely through getting the sound.
2. If you are using Red Hat 9.0, the kernel which comes with it will probably have some EXTRAVERSION (for e.g. 2.4.20-13-9). It is not necessary to compile this kernel, since it most probably comes with soundcore module. Do a modinfo soundcore. If this returns some message:
[shashank@mia alsa]# modinfo soundcore
filename: /lib/modules/2.4.20/kernel/dri vers/ sound/soundcore.o
description : "Core sound module"
author: "Alan Cox"
license: "GPL"
then you are safe, and you do not have to download/recompile the kernel. But I prefer to use the stock linux kernel, hence all the below instructions will apply to a stock kernel (v2.4.20). You can download this from www.kernel.org.
3. After downloading the kernel, put it in /usr/src/ and untar/unzip it using tar -xvjf linux-2.4.20.tar.bz2. You will get a directory /usr/src/linux-2.4.20. Make a link to this directory using the following command:
#>ln -s /usr/src/linux-2.4.20 /usr/src/linux
4. Now start compiling the kernel. I have mentioned the detailed instructions here, but you need to make a few changes in some steps.
#>cd /usr/src/linux-2.4.20
#>make clean; make mrproper
#>cp /boot/config-2.4.20-13.9 .config
#>make menuconfig
Turn off the following option (If you want to have philips camera too. In my case, i had)
Loadable Module Support --> Set Version Information on All module Symbols
sound --> Sound Card Support
(I have also kept everything else as Modules, as my camera refused to work for some unknown reasons.)
In addition check if the following options are selected. (Most probably they are)
USB support --> Support of USB
--> UHCI (Intel PIIX4, VIA, ...)
--> USB Audio support
--> USB Philips Cameras
Then complete the final step as :
#>make dep; make bzImage; make modules; make modules_install; make install
When the compilation is complete, reboot the system in the new kernel (2.4.20).
5. The first thing to do now is to identify the sound card that you have. In my case, I had a sound card integrated on my motherboard. However an lspci -vvv command will give u much detail of your sound card.
#>lspci -vvv
--SNIP--

--SNIP--
Thus from the above output you can see that I have an Intel Corp. 82801DB AC'97 Audio Controller. This information should be sufficient for installing alsa-drivers.
6. Now make a directory /usr/src/alsa and copy the following script install.sh to that directory. Since this is a simple bash script, make appropriate changes to the version. I am using the latest version (0.9.4 at the time of this writing).
