Oh not again
As crazy as the idea of forcing A/D converters to block audio that has been watermarked, in order to close the "analog hole" of copy protection... pushed in the US a few years ago by some politicians firmly in the pay of entertainment industry (never mind the crippling effect this would have on the electronics industry). Fortunately that died. Some such interests are now hard at work, lobbying our dear neighbours south of the Gulf of Finland.
