UPDATE:

I have things working well on OS X 10.5 using the following approach to raise my audio pull pthread to a realtime-like thread:

struct sched_param p;

p.sched_priority = sched_get_priority_max(SCHED_FIFO);

if(pthread_setschedparam(pthread_self(), SCHED_FIFO, &p))

ServerLoger->MakeEntry("Failed to set thread priority.");

On OS X 10.4 however, the sent audio is very broken up. The pthread_setschedparam call is not returning an error however, so I don't know what is different in the pthread library between the OS versions. It appears as if 10.4 is just ignoring the thread schedule change. Any ideas?

Thanks,

Ethan...
