No there was an article on here several months ago that I couldn't find when searching where someone wrote a PoC for the transmission of data via near-ultrasonic sounds from a computer speaker and microphone. I don't think it was this [1] one, but it shows the concept being used.
Maybe I'm misintepreting the OP's work and not realising how it differs in some subtle way? I get that they've put TCP/UDP over it, but is there something else I'm oblivious to?
Also, I meant BadBIOS [2], not Flame.
