Given the messages about the machine not being able to keep up, I
believe there must be some sort of serious misconfiguration of your
system (bad kernel? bad clocking?), because PulseAudio runs just fine on
much less powerful hardware.

It should work fine anyway, but why are you using alsasrc/alsasink
instead of pulsesrc/pulsesink?
