Thanks for the in-depth response, I learned a little bit from you. :)

I’m reminded of the old black hat proof of concepts about reading bits of data via network adapter LEDs, or about listening to sound cards in other rooms doing their signal processing.

I low key kind of love the idea of an evil exfiltration scheme to use a local sound card to receive information about memory contents and then try to pass it somehow desperately over the internet, only now to be thwarted by a mute button. 🤣
