This is an implementation that tries to follow the spec as closely as possible, and works with Qemu's Intel HDA and some bare metal HDA controllers out there. Compiling with `INTEL_HDA_DEBUG=on` will provide a lot of detailed information that could help us getting this to work on more bare metal controllers as well :^) Output format is limited to `i16` samples for now.
