Isn't not swapping page tables during a call precisely what the KPTI mitigations had to turn off for Meltdown mitigations?

That doesn't sound like ring modulation in a musical sense (IIRC it has a modulator above 30 Hz, or inverts the signal instead of attenuating?), so much as crackling, cutting in and out, or an overdone tremolo effect. I checked in Audacity and the signal only gets cut out, not inverted.

TBH I wonder what's going on with the hyper-generic username of "FreelanceProgrammingServices", profile picture, and the HN username of WindowsDev who has made three GitHub submissions of their own work and posted one comment.

The eggshell looks like a century egg, but as mentioned by the comment the contents may have decomposed if the mud wasn't alkaline like the century egg production process.
