fix(audio): actually disable the audio in/out device in settings, when selected

As esecially the "Disabled" text is translated, the audio device will change from "disabled" to "default", just by changing the language.

In contrast to video devices, an audio device is either always available, or sound will be disabled. So "Disabled" is the correct term to use here.
