There's a simple heuristic in PA that initially if we have no prior
configuration we prefer PCI over USB under the assumption that PCI
might be built-in while USB is not. I think usually that is the right
approach, but in your case it might not be.

You should be able to use g-v-c to select the usb mike as
default. That will rewrite the entire database for all saved streams.

Uh, that is weird. Possibly because USB initialization is asynchronous
these days it isnt right-away available when PA starts up?
