It would basically be the same set of syscalls as done from user space.
You would save the overhead of user space context switching, but the
system call delays would not be saved. If you really want to avoid the
system call delays, you would need to have your code replicate all that
is done in those system calls, and this would be a monumental task.

Audio at 96 kHz is trivial compared to something like video. Yet video
is easily handled from user space on machines as slow as 400 MHz. What
kind of machine is this you are using?
