At least for me, Windows 11 has started to automatically add Voice Clarity "enhancements" to the mic. This completely threw off my calibration and the results sounded horrible. This wasn't an issue a several months ago. I noticed this turned on about 2 months ago during my last calibration. I thought maybe it was a fluke. I am getting ready to calibrate again and these settings were turned on again. So, double check the mic settings so you don't waste as much time as I did.
