A while back I asked on this list if there was any way to get post-mix
audio, and I found out that the post-mix audio is only available to the
audio driver. I have been looking into writing a lightweight driver that
just gives me the audio that would have been output by the computer, but I
am concerned about one point; how can I get the driver to load and show up
as an option if it doesn't match against any hardware?
I believe that the standard way an audio driver gets created is because
its plist matches something in the ioRegistry; if I match against some
piece of audio hardware with my driver, it would both create an odd
dependance on some unnecessary hardware and prevent the real driver for
that device from getting loaded. Are there any alternatives, like some
way to mark an audio driver as "virtual" so it has no hardware dependence,
or perhaps something harmless for me to match against in the ioRegistry?
Or do I have this all wrong?
Any tips appreciated!
Thanks,
