Buried in Intel ICH10 Errata update: HD audio “oversampling” setting in all Intel chipsets to use for SDR, Tx up to 2.3Mhz (48bit@48Khz), Rx to 4.6 Mhz (96b). Even without tuned antenna has range to cover LF and MF incl.160m (1.8-2.2) amateur band! https://www.intel.ca/content/dam/www/public/us/en/documents/specification-updates/io-controller-hub-10-family-specification-update.pdf …

You still need to remove antialiasing and reconstruction lowpasses.
This isn't even oversampling. He's confusing the stream bandwidth on a *digital* link which is intended for *multiple* multiplexed channels with analog oversampling. Oversampling has nothing whatsoever to do with what he found. Zero. Nada.

absolutely unpossible. no way. can't be done. :-) well until you can.

Your claim is literally akin to "you can plug in an SDR into a USB port therefore every USB port is an SDR". Call me when you find a mainstream *codec IC* that can actually sample faster than 192kHz for SDR.
