There isn't any mechanisms to do what you need to do outside of the kernel. The current HAL plug-in's are there solely for IOAudio family drivers and don't have access to the IO pipeline.

I'm looking for a way to route the audio output of generic applications over IP. If I understand it correctly, audio output can usually happen to one of the Devices that a call to

AudioHardwareGetProperty ( kAudioHardwarePropertyDevices, &theSize, theDeviceList )

returns. Is there a way to get into the list without writing a full blown Audio Driver? An Audio Driver would be a KEXT with all the ugly consequences (two machines needed for debugging, memory access violations cause the OS to crash etc.)
