I'm not an OpenSuSE user (Gentoo) nor a pulseaudio user (straight alsa, 
phonon-vlc as the kde/phonon backend), but here's a simple trick that may 
well fix it for you, given the above:

Those kmix config files?  Instead of deleting them, truncate them to zero 
bytes (delete everything in them, or delete them and then touch them to 
recreate @ 0 bytes), then set permissions on them read-only.  (I've used 
this trick to good effect with a number of other kde uncooperatives.  If 
they can't write the bad config...)

If that doesn't work (it might not depending on the config saving 
mechanism) try setting them to root ownership and read-only.

If that doesn't work (depending on the technique used by config-saving 
mechanism, you may need to set perms on the containing directory, which 
isn't ideal given its a general kde config dir, not kmix specific), 
there's three more complex options you might be able to try depending on 
how your system is setup:

If the filesystem in question is ext2/3/4 based, consider setting the 
files in question "immutable".  (FWIW I've never done this as I run 
reiserfs here and IIRC it doesn't have an immutable bit, but it's an 
interesting concept.)

If your system runs SELinux security contexts, you can try editing the 
security contexts of the files so kmix can't touch them.  (Again, no 
selinux here so I've not actually tried it.)

Setup a script that deletes the files either as part of the login process, 
before kmix is up and running to read them, or perhaps as part of the 
logout process.  (I HAVE done this sort of thing, before, actually 
somewhat frequently, as because the technique simply runs a script, it's 
as flexible as the commands I can run from a script. =:^)
