3 of 6 does essentially the step you call #4 and #2, other steps is just fixes I already have in my tree.
Tested quite extensively too

The other steps I have already done in a followup series, except #1, it's unneeded.
It also breaks device->pwfx = NULL in the initial case, which is nice to see if something
depends on the new format before changing over is complete. This would otherwise
be very hardto detect.

I'm surprised you call #2 a separate step since from what I gathered about
mmdevapi is that until win7 sp1 it only supported 1 rate, and we don't
implement the rate changing extension yet, so the whole popular format
testing was pointless to begin with.

Is there anything *technically* wrong with the patch series though?
