Dithering of an audiofrequency signal typically occurs at what stage?

The self-induced back voltage in a circuit that occurs when an inductive DC circuit is opened may be safely routed away from the switch with a diode connected across the inductor and against the DC voltage. What is the main disadvantage of this practice?
