So I'm dealing with this issue right now. I just upgraded to Windows 11 5 days ago and before that, everything worked fine on my end. Now, audacity records slowly (i.e 1 second in audacity takes 4-5 seconds in real life), and the audio comes out extremely distorted, and as you described, like Atari levels of pixellation, as well as high pitched.
I won't deny I'm not a computer whiz, but I've tried taking this "x64.7z" you posted here on Jan 19, 2022, and then tried following your steps. All seemed fine until:
this part. When I chose "Have Disk", it only gave me the option to select one single file within the x64 folder you provided. Upon choosing one, it then warned me that this file may make my entire computer malfunction, which is the last thing I need right now. Can you possible add any more clarification to help out? My work-from-home voice studio is banking on this and until I get this fixed, I am screwed. Any help is immensely appreciated.
