How to select sound output (KDE5)

Hi

Just upgraded my OpenSUSE box and thus got Plasma5 (I guess).

I have several possible sound output on my PC and often change from 
listening in headphones to loudspeakers. Before upgrading I could open 
kmix from the little icon in the bottom of the screen, locate the sound 
source, right click and select move. Although this took several mouse 
actions it was possible.

How is this supposed to be done in the new KDE? I see kmix is still 
available but if started I get 2 sound icons in the  bottom bar. Should 
I just go for the olsd one and kill the new plasma mixer thing or is 
there a new intuitive way to move the sound around?
