I've recieved many questions asking me about alsa configuring,, so (i have sound blaster live 5.1 platinum)
here is the exact steps i've done to get it to work

1-download alsa driver, libs, and utils
2-configure alsa driver with the following command :

#./configure --with-cards=emu10k1 --with-sequencer=yes;make;make install

3- run ./snddevices

4-install the alsa-lib package

#./configure;make;make install

5- rebeat the above step for alsa utils

6-i've rebooted the pc , after the reboot i've tried alsamixer and it did not started, so i had to add the following to my /etc/modules.conf

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

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

# card #1
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

# OSS/Free portion - card #1
alias sound-slot-0 snd-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

# OSS/Free portion - card #2 (cmipci)
alias sound-slot-1 snd-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

then i've rebooted my pc and i've got it to work with out inserting the module

modprobe snd-emu10k1;modprobe snd-pcm-oss;modprobe snd-mixer-oss;modprobe snd-seq-oss
