Definitely the Desktop Environment. It doubt it would be a good idea
to let the kernel handle this, which I suppose you mean with "the

You will then have to configure phonon to use something else than
pulseaudio: just push pulseaudio to the bottom of the list in the
phonon tab, if you are lucky it will work...

Phonon is a multimedia library that can use various daemons and
engines. Of course it can use Pulseaudio, but Pulsaudio is a very ugly
hack. KDE uses Phonon and this is a design decision of the KDE
multimedia developers taken for the following reasons:
Pulseaudio was supposed to replace the old aRts sound
server/mixer/daemon/etc. The idea was good, the implementation not so,
and instead of having a clean sound mixing daemon working flawlessly,
we are back in the same problems we had with aRts previously: a overly
cluttered monster full of bugs and badly designed. There is a German
word which describes it very good: "eierlegende Wollmilchsau".
Ask the KDE developers for their opinion about the subject, you will
get far less polite answers about Pulseaudio from them than from me...
one of these multimedia devs is sitting right across the table :)
