Are the applications you're testing with getting input from the Sound Manager or directly from CoreAudio?


Directly from CoreAudio, as far as I can tell. I tried Sound Studio, Live, AudioX...

If the apps in question are grabbing data straight from the HAL, there isn't any other processing going on between the driver's Float->Int and the app getting the data in it's IOProc. The HAL doesn't actually touch any of the content.

I don't have any record to disk code on hand, but it would probably be worth your while to write some of your own so that you can verify exactly what you are putting out.
