OK. To what extent needs a codec specific code to work, or is it sufficient
to recognise it as a ac97?

Thank you, I don't know too much about sound hardware, but found it
very neat to see pcm detect the onboard sound of my new P4P800.

Will the MFC be in time for 4.9R ? Murray just posted an update
