Don't know if this is best place to post about this...

Also let me admit that I clearly don't know or understand enough about 
sound issues in Linux. This post is to try to better pin down [with me 
learning in the process]:

1. What is the cause of the problem?

2. What approach to take to correct it?

In KDE 4.4.0 [Mandriva 2010.0 x86_64] and KDE 4.4.1 [Fedora 12 x86_64]. 
When I log out and log back in or reboot when KDE starts sound volume 
levels jump to painfully loud 100% in KMix and pavucontrol. Why is this? 
Is this a KDE, pulseaudio, or alsa issue? As per example I believe that 
openSuSE 11.2 does not use pulseaudio by default for KDE apps [it does 
for Gnome]. I can confirm that this sound jumping to 100% on boot/login 
does not happen in My openSuSE/KDE 4.4.1 partition. I checked and so far 
pulseaudio is not even installed in my openSuSE/KDE 4.4.1.

Work around is to disable or remove pulseaudio:


That doesn't necessarily mean that pulseaudio is at fault or does it? 
Could this be a driver issue?

Some info [using 'alsa-info.sh --no-upload' in Fedora 12 as example]:


What steps could I take or information could I provide to get to the 
bottom of this issue?
