pls help me how to enable sound ??

Looks like the modules for your sound card haven't loaded..

Do you have a file /etc/init.d/alsa ?
Is it set to start at boot?

What's in /etc/modules.conf ? Is your sound card correct there?

[root@localhost root]# cat /etc/modules.conf

probeall usb-interface usb-uhci ehci-hcd
alias ieee1394-controller ohci1394
alias eth0 8139too
above snd-intel8x0 snd-pcm-oss
alias sound-slot-0 snd-intel8x0
[root@localhost root]# /etc/init.d/alsa restart
ALSA driver isn't running.
Starting ALSA version none:modprobe: Can't locate module snd
(intel8x0) [ OK ]
[root@localhost root]#

In a terminal, do dmesg and look for the sound card..

Then modprobe snd-intel8x0
and do dmesg again..

It's a worry that the snd module can't be found..
do depmod -a and post if there are any errors pls.. (shouldn't be)

[root@linux1 student]# modprobe snd-intel8x0
modprobe: Can't locate module snd-intel8x0
[root@linux1 student]# dmesg | grep snd-intel8x0
[root@linux1 student]# locate snd-intel8x0

[root@linux1 pci]# modprobe snd-intel8x0.ko.gz

now what is the problem how to load the module?

That's mighty strange having the modules compressed with gzip!

Are all the modules in the /lib/modules directories like this, .gz ?

do gunzip /lib/modules/2.6.3-7mdk/kernel/sound/pci/snd-intel8x0.ko.gz
and try loading it again..

i have thiserror.

snd-intel8x0.ko: couldn't find the kernel version the module was compiled for
[root@localhost pci]#

I've had a quick look at a Mandrake 10.1 box and it's the same, modules gzipped..
I'll do some tests..

i am very sorry i am having different kernal.

[root@linux1 kernel]# updatedb
[root@linux1 kernel]# locate snd-intel8x0
/lib/modules/2.6.3-7mdk/kernel/sound/pci/snd-intel8x0.ko.gz
[root@linux1 kernel]# uname -a
Linux linux1 2.4.26-openmosix1 #1 Fri Nov 19 22:13:56 CET 2004 i686 unknown unknown GNU/Linux
[root@linux1 kernel]#

so how can i compile my snd-intel8x0.ko.gz for openmosix kernal.

My one loaded ok and added these as well..
snd-ac97-codec snd-pcm snd-timer gameport snd-page-alloc snd-mpu401-uart snd-rawmidi snd-seq-device snd soundcore

Do uname -r pls..
Got to be sure the kernel and modules match..
Did you compile another kernel?

Ok.. you will have a /lib/modules/2.4.26-openmosix1/ directory as well..

If not, go back to your kernel source directory and do make modules_install
and reboot..
The module will have a different name, so make sure it's in /etc/modules.conf

[root@localhost sound]# ls

/lib/modules/2.4.26-openmosix1/kernel/drivers/sound
[root@localhost sound]# make sound.o
make: Nothing to be done for `sound.o'.
[root@localhost sound]#

Ok.. the module you need is i810_audio
do modprobe i810_audio
then look at dmesg again..
if it works ok and loads a whole lot more modules, you should be closer..

Usually, the start scripts for 2.6 kernels are different for 2.4 kernels, so I'd recommend doing the openmosix patch with a 2.6 kernel..
The alsa scripts are different for sure..

it seems loaded.
that is all or should install further modules.
should i reboot my computer.?
