Intel's HDA is _not_ a different codec, but a completely new design of the sound engine. Linux and NetBSD people have already written support for that engine, our haven't yet. Also, I don't like Intel's police to license all HDA implementations, read http://www.intel.com/standards/hdaudio/ Implementation of the High Definition Audio Specification requires a license from Intel. Contributors to the High Definition Audio Specification have signed the High Definition Audio (Azalia) Developers Agreement and have provided input to the specification under the terms outlined in that agreement. Implementers that have signed the High Definition Audio Specification (Azalia) Adopter Agreement are licensed to produce products based on the specification under a reciprocal, royalty-free license to certain intellectual property rights from Intel and other Contributors and Adopters for their products that are compliant with the licensed versions of the High Definition Audio Specification. It sounds somehow restrictive, doesn't it? But NetBSD people have done it, so I think FreeBSD people should be able to do it also. There is an increasing bunch of new Intel's hardware which provides HDA as the only sound option, there is simply no other way around it.
