of course it should work, but there's several possible reasons why
it might not.

since he's using KDE anyway, why not use pulseaudio instead? it's
the default for the big DEs, and in my experience it doesn't screw
up one's system anymore, as it used to in the beginning. 

mostly, at least for me, it simply works. specially if you install 
pavucontrol, an interface for all  hard- and software audio
channelsl on your machine.
