Thank you very much. Probably there’s no way to detect inside my driver which
API is actually used and whether it’s in exclusive mode? If it’s only
int->float->int shouldn’t it be bit transparent up to 24 bit integers?
No, because the values in float mode range from -1.0 to +1.0. 32767 maps to
+1.0, so it's not as simple as a bit shift. There's a division.
