User-land CoreAudio driver and Leopard

Hi,

Our user-land CoreAudio driver does not completely work on Leopard:

- it can not be seen as "default input/output" driver for applications like iTunes or QuickTime player that use default input/output devices. What has change under Leopard that could explain this new behaviour?

- we still implement the kAudioHardwarePlugInInterface2ID version of the AudioHardwarePlugIn.h header, but the header has now a kAudioHardwarePlugInInterface4ID version whith much more functions. Can we stay with the kAudioHardwarePlugInInterface2ID version?

- some function like AudioHardwareDevicePropertyChanged, AudioHardwareStreamsDied... are now deprecated. What has to be used instead?

Thanks

Stephane Letz
