I looked through those threads. The first solved his problem by disabling some nvidia power management feature that caused glitches with his $300 "professional" external audio interface. The second is someone struggling with his $999 quad DSP board and the third is yet another high end external audio system.
That sort of high end audiophile grade stuff is never glitch free. You and the other 8 people on Earth attempting to operate your external quad DSP board are expected to cope with such things. The other 99.999% of us are just running ordinary cmedia xonar, realtek or whatnot audio and have zero problems with NVidia. If you are going to wade into that audiophile mess you need to man up and deal with the glitches.
Whether you do or not at least I'm convinced your concerns are irreverent to almost everyone else.
