I have been directed to the appropriate Intel spec manuals. I should
probably have gone there first, but I never guessed that 'not-working'
sound could be so complex.

But your suggestion directed me to up dating my BIOS which was probably
needed anyway.

Well I have largely ignored sound and sound devices most of my life, so
delving into this stuff both technically and theoretically have been an
adventure. One that I intend to pursue. Luckily I don't have to cram
it all in. I have the time to learn something; put it aside; think
about it; then go back for more.
