I am not aware of that RME has or distinguishes between 32 and 64 bit drivers.
Could you kindly tell, which file you downloaded and installed?
From what I can see, the MADIface uses the same driver as, e.g., UFX+ and many other current interfaces.

According to the README, the last change for the MADIface USB in this driver was in v 0.9609, April 2017.
As this is no complex interface with plenty of port types, this looks fair enough to be called, up-to-date enough.
More details, please, error messages, … Maybe a screenshot of the configuration of the RME ASIO driver in foobar v2.
Did you already cross-check with the old / mature foobar v1.x? Maybe a bug in the new v2?
