Before installing this driver, it will be helpful to read carefully
the documentation for insmod, modprobe, kmod and for the isapnp
module if you have an ISA PnP soundcard.

Skip this step, if you have a kernel with the DEVFS support.
7) Edit your /etc/modules.conf (see the kmod support section below).
8) Run 'modprobe snd-xxxx' where xxxx is the name of your card.

2) If you have got ISA PnP soundcard:

+Autoloading on Older Kernels
+============================
+
+On 2.2 or 2.4 kernels, you have to set the additional aliases for
+auto-loading via kmod in /etc/modules.conf:
-http://www.alsa-project.org/cgi-bin/bugs
+----- /etc/modules.conf
+# ALSA portion
+alias char-major-116 snd
+# OSS/Free portion
+alias char-major-14 soundcore
+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
+----- /etc/modules.conf
+
+The aliases sound-service-x-y define the add-on modules for ALSA
+OSS emulation. For the second or later card, define more aliases
+for mixer and pcm in addition, such as:
+
+----- /etc/modules.conf
+# 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
+----- /etc/modules.conf
+
+You don't need to define service 1 and 8 for the second or later
+cards.
+If you want to autoclean your modules, you should put below line to your
+/etc/crontab:
-Module parameters
-=================
+*/10 * * * * root /sbin/modprobe -rs snd-card-0 snd-card-1; /sbin/rmmod -as
-For the drivers already integrated into 2.5 kernel tree, please see
-alsa-kernel/Documentation/ALSA-Configuration.txt
+You may also want to extend the soundcard list to follow your requirements.
