Ah, you mean dynamically. The question is, whether a DCOP call would really 
solve your needs. If you do it during the login phase of the user, KMix might 
not be completely up.  OTOH you want to have it as soon as possible.

The only reliable option for today is to modify "MasterMixer" and 
"MasterMixerDevice" in the users kmixrc configuration file. This  has to be 
done before KMix is launched for the user (this could mean to modify the 
startkde script).

It wouldn't help in this case. But in general, you should consider doing that, 
as work on various components (incl. KMix) has been stopped on the KDE3 
branch. I am personally running a fine mix of the KDE4 desktop sprinkled with 
some KDE3 apps.
