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

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.

[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..

[root@linux1 tcptraceroute-1.4]# modprobe i810_audio
[root@linux1 tcptraceroute-1.4]#


[root@linux1 tcptraceroute-1.4]# dmesg | grep i810_audio

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

You're back to the old 2.4 config now.. which uses OSS rather than alsa.
You will need to install the alsa-2.4 packages to get it to work..

Sound devices should work if they use /dev/dsp
It is an oss device..

What you have now is a 2.6 installation using a 2.4 kernel..

Be prepared for lots of strange things to not work.
You may have packages built for alsa in the 2.6 kernel, and the only way to get them to work is to install either the 2.4-alsa packages or the 2.4 version of the package..

It's going to be easier overall to make another 2.6 kernel.. (it would be my personal choice).

THANKS.
