I'm trying to feed audio from my user-space driver into CoreAudio.
There seems to be an interplay between the IO buffer size I use in
HALLab and the ring buffer size in my driver.
Regardless of the sizes I use, I get gaps in the audio that HALLab saves.
Am I doing something obviously wrong here?
Thanks, Joel
