I am unable to make any sound at all from the speaker with tests or any other way.
To check that hardware is basically OK, I installed Slackware-14.0 again on a separate traditional (non-LVM) partition and setup a dual boot. When I boot from the non-LVM partition, sound works fine with no error messages from KDE.
Both boot methods use the kernel: vmlinuz-huge-smp-3.2.29-smp
The LVM boot uses an initrd during boot however, and this may be the cause of the problem. I created the initrd with the command:
Location: Somewhere inside 9.9 million sq. km. Canada
Distribution: Slackware 14.1
I think the first thing to do is make sure the correct sound driver is loaded for your card when failing.
Do you know what the correct driver is? If not, run the command 'lspci' and post the line for the audio hardware. If you know what the driver is, run 'lsmod' and confirm the driver is loaded, when failing.
Have you run a mixer, and made sure you are not muted, and the volume is turned up? alsamixer should show you this.
I believe that means that there aren't any clients for snd_via82xx. I hope that is a clue.
I ran lscpi using both boots and I got identical results. I list the result below.
Thanks for your help!

My installation of Slackware_14.0 using LVM is still not quite working.
To recap, I installed Slackware_14.0 on LVM partitions and sound was not working.
Then I installed Slackware_14.0 again, on the same X86 machine using tradition partitions.
Then I arranged for dual booting from either installation. On both I used the slackware installer and answered all questions except those about partitioning the same way.
The strange thing is that sound works fine with my "traditional partition" but but sound doesn't work when booted from the LVM partition though the two installations are as alike as possible.
For both installations I edited the /etc/inittab file so as to start X automatically.
I changed lines in that file to read:
# Default runlevel. (Do not set to 0 or 6)
Now I have noticed that when I change this back to starting runlevel 3, and then using
startx after the boot, sound does work properly even from my LVM partition!!!
Can anyone suggest what needs to be done to make sound work when booting direct to runlevel 4?
It turned not to be LVM related.
The problem was that I had set /etc/inittab so as to automatically start X,
and for some reason that stopped sound from working. If I exited X, and
returned to console, then ran startx, the sound would work.o
I asked about this on another thread, and got the advice to add the "audio" group
to my user name using:
usermod -G audio -a <your_user_account>
This solved the problem, and now I boot at run level4 and the sound works!
