 Actually, the order of "play the startup sound" is defined, see 
ksmserver/README.

 No - kmixctrl is a KDE app and pulling in KDE libs early in startkde is a 
no-no.

 I suggest a kcminit module, probably with X-KDE-Init-Phase=0. That will 
easily allow you to handle the condition and will make the position 
of "restore volume levels" in the startup sequence defined as well (which is 
actually the problem - kmixctrl is launched before the startup sound, but 
it's fire&forget, so it takes a while for kmixctrl to actually do its job).
