Just an addendum to this, I have had good support for most of the
on-board Intel HD audio codec vendors, most of which have been generous
enough to send me development boards, and most of them have their codec
specs posted on their web sites. Unfortunately, lately I have been too
overwhelmed with other activities to do much more than read emails, but
I'm almost done with my degree program so I'll be jumping back into the
developers pool soon.

It's the thought, if any, that counts!
