Yes, in theory that should work. of course there's still a possibility that it won't work depending on if the ASIO4ALL didn't "interpret" the WDM soundcard drivers correctly to ASIO 2 format. they're supposed to - but I don't know enough about the "under the hood" stuff of ASIO4ALL to know if it will ALWAYS convert to ASIO2 compliance for every WDM driver.

but from what I understand that's the way it's SUPPOSED to work!
