After installing AMD Noise Suppression, Windows shows that the microphone is always in use by AMD Noise Suppression, even when I an not using it.
This is different from other noise suppression software like NVidia and Krisp, which only capture the microphone when it is actually being used by a program. For example, it should capture the microphone when I start a Teams call, and then release the microphone when I end the call. Those are both events that the microphone driver receives, so it's not hard to do.
There is a good reason for this. When software has captured the microphone, Windows will not sleep. You can see this by running "powercfg /requests" in an administrator CMD prompt:
$ powercfg /requests
DISPLAY:
None.
SYSTEM:
[DRIVER] USB Audio Device (USB\VID_B58E&PID_9E84&MI_00\a&1684c7cb&0&0000)
An audio stream is currently in use.
[DRIVER] Legacy Kernel Caller
[DRIVER] Legacy Kernel Caller
AWAYMODE:
None.
EXECUTION:
None.
PERFBOOST:
None.
ACTIVELOCKSCREEN:
None.
Windows will not sleep while there is anything in this list. That audio device is AMD Noise Suppression, and that is a big problem.
