no sound after?

[Perry]

Hi,


I have been battling for days with sound problem. I made many reinstall to pin 
down the cause, rebooting after each operation.

I checked kmix, the strange thing is it has no button under pcm...it would 
take me another reinstall to check wether it dissepeared or newer was there, 
unless someone can confirm there is no button there.

I tried renaming .kde to no avail.

*Symptoms*
On fresh install KUbuntu Hary I have the "greeting sound" when I log in.
I can reboot, change screen from p&p to generic, reboot, install Firefox with 
adept, reboot...and still have the greeting sound. (Warning: /home partition 
was not reformatted)

What appeared once to kill it was when I watched some dailymotion stuff on 
firefox.
I could then "ctrl-alt-backspace" and still get the greeting sound, but it is 
was gone after a reboot.
I thought I had it!
But on another trial I installed the updates first, rebooted and the sound was 
gone on next (compulsory because of kernel) reboot.

It is not that I care about this sound, but I have no sound at all.

There is a lot of documentation on sound problem, but very little pertinent 
for my problem, and nothing I tried worked.

I can list the output of some commands, but I'm unsure it will help until I 
understand what causes the sound to dissepear.

Any idea?

P.S. I thought it was wise to install the LTS Hardy, I tried Kubuntu 9 on 
another partition, liked it less, but it still has sound working.
Would you advise me to to use Kubuntu 9 instead of Hardy?

Thanks for any pointer or opinion.
