... on Audigy, when we are not pitch-shifting.
The only observable effect is that the Z1/Z2/FXBUS registers don't have
a stray bit set for negative numbers anymore. The bit is below the ones
significant for output, but it would mess with 32-bit sample
recombination, which we are about to add.
kX-project does that, but I had to figure out myself why.
