AVSSAMP example not working

hi, thanks for these samples, I would like to create a virtual camera with both video & audio, and perhaps some decoding functions

avshws working for me but got no sound, then I try avssamp. it builds successfuly, but not working.

I am using win11, got windows driver kit 10 installed, and have the cer file registered to root after that i tried:

1. using hdwwiz, after choosing inf file, got no option to continue

2. try using devcon to register, it succeed, but unable to play

i created a avssamp.wav with my ffmpeg using pcm16le format, 1 channel, 44100hz, im sure it's valid

could you let me know if anything I config wrong
