LinuxQuestions.org - Alsa OSS emulation problem

I'm trying alsa for the first time and I'm having the first problem. When I try to use the oss emulation there is not sound, there is not even the device /dev/mixer and /dev/dsp.
Here is my Modules.conf

Code:

### modules-update: start processing /etc/modules.d/alsa

# Alsa 0.9.X kernel modules' configuration file.

# $Header: /home/cvsroot/gentoo-x86/media-sound/alsa-utils/files/alsa-modules.con$



# ALSA portion

alias char-major-116 snd

# OSS/Free portion

alias char-major-14 soundcore



##

## IMPORTANT:

## You need to customise this section for your specific sound card(s)

## and then run `update-modules' command.

## Read alsa-driver's INSTALL file in /usr/share/doc for more info.

##

##  ALSA portion

alias snd-card-0 snd-intel8x0

## alias snd-card-1 snd-ens1371

##  OSS/Free portion

alias sound-slot-0 snd-card-0

## alias sound-slot-1 snd-card-1

##



# OSS/Free portion - 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 #2

## alias sound-service-1-0 snd-mixer-oss

## alias sound-service-1-3 snd-pcm-oss

## alias sound-service-1-12 snd-pcm-oss



alias /dev/mixer snd-mixer-oss

alias /dev/dsp snd-pcm-oss

alias /dev/midi snd-seq-oss



# Set this to the correct number of cards.

options snd cards_limit=1



### modules-update: end processing /etc/modules.d/alsa

BTW I'm using gentoo linux and I have installed alsa-driver, alsa-utils, and alsa-oss acording the the gentoo alsa install guide http://www.gentoo.org/doc/en/alsa-guide.xml
