Galvanic Switch for Mic and Speakers?

[98'1093481'029348'1092438'0914328]

Hello,

perhaps an galvanic switch is not only useful for the Mic (and a shutter for the cam), but also for the speakers...

Hardly a "new" piece of news: that's why airgapped computers typically
don't have either microphones nor speakers.

As an example, here's what our Rutkowska did to her iphone in 2014:

(the iphone is used via a bluetooth headset that can be switched off
with 100% security)
