I don't think so, I mean the sample period for the channel dictates when the instantaneous value at the DAC should change and the volume control's switching the whole thing on and off to control the volume is immediately averaged out by the filtering. It may even be smoothed out before it even reaches any of the dedicated filters just by some of the basic circuit characteristics of the analogue stage. I'm not intimately familiar with them but I'd assume there's be some overall capacitance that might soften the harsh on/off transitions.
