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

etc.)
affect the floating point formatting in the IOProc or do these just
apply to the
stream hardware formatting ?
Thanks,
