Running FluidSynth example in GDB yields the following for me:

[New Thread 16384 (LWP 1217)]
fluidsynth: ALSA driver: Using format s16, rw, interleaved

[New Thread 32769 (LWP 1311)]
fluidsynth: warning: Couldn't set high priority scheduling for the audio output

Perhaps this should be sent to FluidSYnth development list.
I have alsa-lib-1.0.8rc2, kernel 2.6.9 and FluidSYnth-1.0.5.
