this is still fading, but not nearly as badly. fail.
i'm going to try with the wmi driver extensions turned on. then do the reinstall with it on, & etc.
this is a mild enough fade that i may have not noticed it before. but it's there.
it's becoming clear that i may have to re-upload some material from last year. i've known since the start that the files sound slightly different on the laptop, but i just assumed it was because it's a laptop.
