Why does this use up about 5% CPU (on my system) (pseude code of course)
while (data,size = get_data) { write(/dev/dsp,data,size); }
And this only uses about 0%:
while (data,size = get_data) { write(/dev/dsp,data,size); usleep(1); }
I've also tried replacing the usleep with sched_yield() but that did nothing.
