grab raw data from microphone and send it to the output

[Ivan Riabtsov]

Hello. There is a task to receive raw data from the microphone and,
after some processing, send it to the output (headphones or speakers)
to speed up the process, I want to do this at the kernel space, please
tell me where to start (which way to look and what to read)? My sound
device: "Family 17h (Models 10h-1fh) HD Audio Controller".
Thanks Everyone
