Weren’t they pretty straight up saying it was a microcode issue with a patch coming out? Affecting 65 watt+ CPUs which also wasn’t in the limelight since only the high end i7/i9 CPUs were seeing significant failures being reported. I’d imagine a mini PC would be pretty safe.
I’m not 100% on the pitching down bit, but key would be to get a mic that has those frequencies in its range.
