Is this behavior expected to be consistent no matter which direction the volume is being adjusted? I wouldn't expect a firmware update to address the properties and behavior of an analog/"physical" device, but if there is an issue with the digital display of the current status of the analog physical device as is the case here, then it *could* be a firmware thing I think, I dunno, I have a lot of reading and testing yet to do . P.S. by consistent I mean that the "jumping" will be consistent in the flat points (i.e. that going from -12->-12.5 should always have the same size jump), and therefore *potentially* the position of the volume knob should always be consistent with a certain volume setting assuming the physical volume control position is synchronized with the volume level indication. I am not meaning that the size of the jumps will be consistent across the range of adjustment. If volume knob position does not correlate to true volume level, then I think having the little value indication hash mark on the volume knob is misleading, it should just be a faceless knob like most of my other gear, THAT could also fix it .
