I saw the awful measurements of Windows 10 resampling on archimago's site here: http://archimago.blogspot.com/2015/11/measurements-windows-10-audio-stack.html
and I figured I would test this for myself. I see quite a few people pointing to that article when they say Windows resampling sucks, and I feel like results like that should be very audible, whereas i don't really hear that big of a difference if at all. I only have a crappy laptop ADC, but it should still be able to capture the awful results shown in the article.
Setup is Geekout 1000 connected to one laptop with the standard Windows UAC2 audio driver and latest updates installed, outputting 19+20khz sines via ARTA through DirectSound at various samplerates, then running the output through my Fiio A5 to attenuate the signal, into the ADC of my other laptop which is recording the result at 96khz and displaying in ARTA.
Well, behold. 44 -> 96khz resampling through Windows.
Nothing even close to the results in the article, tho not spectacular either. Keep in mind that most of these spikes are caused by the craptastic ADC rather than the resampler. Here is non-resampled output for reference:
I did a bunch of other combinations of samplerates as well, attached to this post. Just about the only results that were meaningfully worse were the 44->48 and 48->44 tests, IMO.
User Case on Hydrogenaudio got similar results here: https://hydrogenaud.io/index.php/topic,114138.msg940216.html#msg940216
In conclusion, I think there is nothing to worry about with Windows resampling.
