Can you clarify what the "default sink" section is? PulseAudio GUIs are
generally the domain of the desktop environment which uses it, so this
could be a GNOME or KDE specific tool.

How did you manually set it? And what do you mean by it didn't work? If
you set the default, does it not show as the default or do you just mean
that programs are not using it as their default and are still using the
built in hardware? Keep in mind that the "default" in PA terms is not
really used unless all other routing options are exhausted. Changing the
default will not move active streams (well the GNOME GUI does this, but
it's a not something PA does itself).

If you could give more details I can advice more.

Keep in mind that the Airport support is still rather rubbish in lots of
ways (I say this as the author!) and does still need work. Timing and
buffering in particular.

Cheers
