Expected Behavior

Same as in OBS 29.x:
The NVIDIA Noise Removal filter should always work at every selected value.

Current Behavior

Adding the Noise Suppression Filter to an audio source and then selecting the "NVIDIA Noise Removal" option makes the filter work at 100% (value 1.0). Changing the value causes the filter to stop working completely, even when reverting to value 1.0. Restarting OBS, while the filter is still active regardless of the value, makes the filter work again, but only at 100%/1.0, even if a different value was selected beforehand.

Steps to Reproduce

1. Add the Noise Supression Filter to an audio source
2. Select NVIDIA Noise Removal
3. Change the value
4. Filter stops working

Anything else we should know?

Started happening after updating to OBS 30.
NVIDIA Audio SDK is updated to the latest version.
This bug is probably related to these lines in the log file:
[noise suppress: 'Noise Suppression'] NvAFX_Load() failed with error 1
[noise suppress: 'Noise Suppression'] NvAFX_Release() failed
[noise suppress: 'Noise Suppression'] NVAFX SDK redist path was found here C:\Program Files\NVIDIA Corporation\NVIDIA Audio Effects SDK

Start by reproducing the failure on Windows 10 with OBS 30.1.2, then inspect the linked OBS log for the NvAFX_Load and NvAFX_Release errors and compare the behavior with OBS 29.x. The NVIDIA Audio Effects SDK integration is the relevant entry point mentioned by the report. Done means changing the NVIDIA Noise Removal value no longer disables the filter, including after reverting the value, with the regression verified.
