The kcontrol 'DSP VAD Switch' is automatically enabled/disabled when the hotwording PCM stream is opened/closed.
So why do we have the switch?
The source of the switch is commit af48f1d08a547 ("ASoC: rt5677: Support DSP function for VAD application") and does not explain the original intent of the switch. I believe the original intent of this commit is to keep the switch in sync with the VAD state. I do not believe we use the switch ourselves.
