Get/Set Master Volume Lautstärke?

[Kas Ob.]

My two cents on this, Mute and Enable are intentionally undocumented by Microsoft, these will compromise the user privacy, like .. by simply enabling the disabled microphone in first place, or just unmute the speakers without the user consent and play some audio.

It is doable and it is not a hack, but unethical to share, so you have to ask the user himself to enable (eg. the Mic) or unmute the speakers.
