I'd also be interested in that. However at present I've deal with such
matters by having mutliple (non computer) recorders and sources. I still
tend to have the old-fashioned view that it is simpler and better to have
the recorders and sources divorced from a computer whos hardware and
software is subject to continual 'updates and changes' that mean you'd have
to keep re-calibrating and checking if the audio i/o was still working
correctly.

So USE a computer that you choose not to modify or update. D'oh!
