Correct, most drivers mute when the audio stops.
If I use the Realtek drivers, the audio is muted when playback stops.
If I use the Microsoft Hi Def drivers only, a constant stream of zero’s is send.
I can notice the difference because my DAC (Benchmark) mutes after 15 seconds of no signal.
In case of the Realtek, it mutes, in case of the MS drivers it stays on.
Of course like any well designed gear, it won’t cause any audible click when activated or muted.
