One problem: the gain settings have changed, now having a range of 0..64.
How do these values map to the internal ones (0..0xffff) ? I *hope* there
is value corresponding to EXACTLY 0x8000 (gain = 1) !!! The reason is
that MADI is bit-exact and is used to tranport other values than just
audio samples. This works of course only with exact unity gain.
BTW, why was this change made ? For pro users (are there other of this
card) this is a regression.
