Everything about the ASBDs returned via kAudioDevicePropertyStreamFormat and friends applies. You should be paying attention to everything they say.

If you are doing output, you should probably be using the HAL output Audio Unit. It will take care of a lot of the work that goes in to being a client of the HAL. It also interfaces with the AudioConverter to massage the data into the form the device wants.

In AudioHardware.h, it states that linear PCM streams are presented as floating point
data in the IOProc. Do the stream format flags (big endian, packed etc.)
affect the floating point formatting in the IOProc or do these just apply to the
stream hardware formatting ?

Thanks,
