Did you look at creating a user-space audio driver instead of the kernel one? 10.9+ only, but if you built this recently it probably makes a lot more sense.

Thanks for the link. I went with a kernel driver because I knew that approach would work on old OSX (starting with 10.5), but since i'm delivering two kexts anyway, switching to an user-space driver for 10.9+ would probably reduce CPU usage :)
