Thank you! I had to patch it manually, too, and in attachment here's the
patch I made: apply with

patch -p1 </path/to/fusd-kor-1.10-9_kernel_2.6.13_patch

It really depends on the application. Good results are with (according
to info on website):

     * mplayer
     * artsd (and thus all the kde applications)
     * xmms
     * Macromedia Flash
     * xine
     * Totem
     * esd
     * SoundTracker
     * Frozen Bubble
     * GStreamer (osssink)
     * Quake 3
     * Audacity
     * Skype

I dind't manage to make it work with Audacity, though...
With Skype I had no problem:
