[wdmaudiodev] System and application sounds difference?

Cool, I've hit an undocumented Vista "feature". At least there is no trace of the 
"feature" in Sound Control Panel...

Short story: In order to get as transparent a user experience as possible, my 
UM application on startup selects my VAD device as default device
and on exit reverts to the previous device. Works fine. On Vista. Seriously ;)

Well, semi-fine really since my switch implementation seems to only reroute sounds from 
applications (other than windows). The system sounds, f.i. the little "click" 
when you browse in explorer, are still routed to the old default device, whereas WMP f.i. 
is routed to my device (which
incidentally _is_ shown as the default device in Sound Control Panel).

If I choose the default device via Sound Control panel instead, all sounds go 
to the selected device, so obviously my implementation is
incomplete (due to lacking information/documentation).

Anyone care to share some insights here ?
