Easy enough:

dmix is set by standard as of ALSA 1.0.9rc2 [1]

but getfacl shows that only one of my users is added to the ACL list for 
device files in /dev/snd. Whyever...

So its going to be the good old way around: I added both users to group 
audio. I removed them from there for the perfect pulseaudio setup.

Now I get simultaneous audio on both sessions without a glitch. And 
frankly I don´t care whether thats by design or not. I even don´t care 
about the recording issue for these two users, cause they are both mine.

A mailing list reader suggested a VM for the second user, but all I just 
want is two KDE sessions with audio simultaneously and now I just got want 
I wanted. Why use a VM when its not needed?

I still hope that Pulseaudio can give me this by a simple configuration 
option one time. I stand by it that this is a perfectly valid setup and do 
not want to dictacted to organize my stuff differently by software or 
design.
