I'll try to find out. > Can two muxes use the same bit in the hardware without problems? IIRC we fixed things so that if you've got two controls that share the same register we do the right thing. There are other devices with this issue but it was years ago that I last looked at them, we do have handling. > > Those are not volume it's gain, > We tried to call the things ..."

Yes, this is part of the ABI and honestly from an end user point of view there is no meaningful difference between the two words (there would be more if it were gain and attenuation since one is amplification and the other isn't so there are different considerations when applying them to signals but that's not the case here).
