Coming from the host-development side (which we do with a small handful of our products, Rax in particular), I can tell you that we HAVE tried this and researched it, and our roadblock in the end is the AUHAL drivers.

If you really care about high-quality output I'm surprised that you are leaving float->int conversion to AUHAL or the audio drivers. Nothing against AUHAL, just that trusting the OS to do this doesn't seem like the right approach if you care about a well defined audio pathway.

I would do the ffloat -> int conversion in the host and use a hardware supported bit depth at the interface to AUHAL. That way you have full control over dithering algorithms etc.
