Crash-course ultra-mini-howto on installing ALSA from source:

1.- Get the packages from http://alsa-project.org . You should get the 
packages alsa-driver, alsa-utils, alsa-lib, alsa-oss and depending on 
your hardware, you may or may not want to download alsa-tools (basically 
useful for Envy24, EMU10K1, SB16/AWE and some others)

2.- Decompress the packages, to ease this process, I usually use this 
'for' loop in bash:
for i in *.tar.bz2; do tar jxf $i; done

3.- Install in this order: alsa-lib, alsa-utils, alsa-oss, alsa-driver, 
I usually leave the alsa-driver 'till the end to make sure everything's 
up and running, like alsamixer. Install with the famous triad:
./configure && make && sudo make install
Note: if your user is not a sudoer, then you will have to su to root to 
install.

4.- Prior to installing the driver, I usually first configure my 
modprobe.conf file, you should have something like this:

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-emu10k1
alias snd-card-1 snd-intel8x0
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
# card #0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
# card 1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss

NOTE: Here I have two cards configured, and the lines created by 
system-config-soundcard are commented out (in your case may be missing). 
For your particular setup, these lines shouldbe something like this:

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-azx
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

5.- Install the driver, basically just as the other packages, but you 
will have to tell configure what you want:
./confgure --with-cards=azx --with-oss=yes (if you want oss emulation 
capabilities, highly recommended) --with-sequencer=yes (for MIDI 
support, depends on hardware, you may want to check 
http://alsa.opensrc.org for that) && make && sudo make install

If all went OK, just add the alsasound service:

chkconfig --add alsasound

Just in case create the devices:

./snddevices

Run the service:

/sbin/service alsasound restart

Run alsamixer to set your volumes... Hopefull that's all involved.

It is possible that you will require to install the kernel source, but 
in FC3 this is a little bit difficult, you will have to get the .src.rpm 
of the kernel (I haven't seen any kernel-source package around so if 
there is one, my apologies). Then do the following:
rpm -ivh kernel-<version_etc>.src.rpm
cd /usr/src/redhat/SOURCES
tar jxf -C /usr/src linux-2.6.10.tar.bz2
cd /lib/modules/<your_kernel>
mv build build.bak
ln -s /usr/src/linux-2.6.10 build
and then try to install the drivers again... Yes this is a PITA, but it 
is the ONLY way I know to install the kernel source-code in FC3... Mind 
you that installation my NOT necesarily fail with the standard kernel 
headers in /lib/modules/<kernel>/build/, but may occur.
