There is no import hook for phonon. My understanding is that the phonon
backends use the Qt's plugin system. The import hook takes care of
mentioning the intra-Qt dependencies and the plugins.

Have a look at hooks/hook-PyQt4.QtGui.py for instance, and see if you can
make one for phonon. It's easy to debug: do your build in one-dir mode and
look within the "qt4_plugins" generated directory to see if the backends
are there.
