did you compiled alsa-driver, alsa-lib, alsa-utils or you just did with alsa-driver.
if you follow all the steps in http://www.alsa-project.org you should be able to get the sound.

are you getting any error, for sound, when starting kde..?

hey Virgil, what Linux Distro did you Install?
by Linux 8, do you mean RedHat 8.0?, or whet?

if it is RH, It's weird because it should have detected that sound card during installation, since it is supported fine.

Try updating your kernel...but how new are you to Linux?

hi guys,

thanks for ur reply.

I installled Red Hat 8. The system recognized the sound card, but when I play sound test , no sound.

I compiled alsa-driver, alsa-lib, alsa-utils, i don't get any error while starting linux, the sound volume setup properly. except it fails when run alsamixer
it display error "alsamixer: function snd_ctl_open failed for default: No such file or directory.

thanks,

Installing ALSA for 2.0.x

The ALSA drivers versions 0.3.0, 0.3.1 and 0.3.2 have various problems due to the restructuring of the mixer interface. Later versions do not support kernel 2.0.x, so you definately will want to use version 0.3.0-pre4 if you have a 2.0 version kernel.

Just the all time ``./configure - make - make install'' stuff. Do this for drivers, library and utilities. You need all three because the utilities help you to unmute your card. Kernels 2.0.x need to have all sound support disabled in the kernel setup

The ALSA drivers have their own devices, you can make them usinge the ./snddevices script.

You need to load the module for your card (or use kmod) and if you want sound to be backwards compatible with the Linux kernel sound drivers (yes you want this) you need another modules called snd-pcm1-oss. See the section Which module for which card to find out which module to load. After loading, you can look in /proc/asound for various information about the ALSA drivers.
2.4 Playing and recording sound

A few remarks. ALSA has it's own devices in /dev/snd, for example /dev/snd/pcmC0D1 is Card 0, Device 1. You can use the old /dev/pcmXY devices if you loaded snd-pcm1-oss for backwards compatibility. Before you can play any sound, you need to unmute the card with ``amixer''. Type ``amixer'', then try something like

amixer pcm 100 unmute

Generally you can use options ``mute'' or ``unmute'', ``rec'' or ``norec'', numbers or left:right.

That's it! Now if it works, it works. If it doesn't work, you may need to actually read this HOWTO...

may be u find some thing

You said your sound card was detected but no sound comes out, right? Firstly, the obvious one, did you check the volume levels in a proper mixer and set them ALL to max (my apologies if you did but I saw no refernce to it)? If so, what did you do the test the sound? If you played a CD then that often comes out with silence. You can use xmms with the cdread plugin without any major (re)installation to get around this. If that ll fails then alsa is probably your only salvation.
