erratum sorry: "For the HAL drivers I'm not able to build with 10.7 SDK ..."

For the HAL drivers I'm not able to build with 10.8 SDK (miss some headers in CoreAudio framework) so it does not run on 10.7.
These seems to be like old HardwarePlugin, isn't it?

I talk about a kext because the project contains a kernel extension called SimpleAudioDrvier who should be installed inside System/Library/Extensions ... yep, it sounds strange for a user-land driver.

Thanks for your help Joel.
I gonna install 10.8. But it's really shame if these user-land drivers will be working only on 10.8

Alexis,

These are user-land audio drivers so you need to put them in
/Library/Audio/Plug-Ins/HAL/.

Do that, kill coreaudiod (it will be restarted) and then run HALLab to
see your virtual driver.

I'm sorry but I don't know if these user-land audio drivers will work
with previous versions of Mac OSX.
