Ehm.. seems I was a bit premature. With subsequent tests (and probably more 
stable driver) I can't reproduce the above, i.e. if I tear down
the device, set a new format, and reregister it, it shows up and I can stream 
to it with the new format. Nice.

Seems again I wasn't. The only reason it worked was that I had my Windows Vista default 
format "hack". Without it Windows will only open
my newly destroyed/created device with 44100/2ch/16bits.

Matthew, didn't you say that tearing down the device interface would render 
default format invalid so that Windows should requery the
newly registered device ? Or is IUnregisterSubdevice::UnregisterSubdevice not 
enough to do this ?
