PKEY_FX_KeywordDetector_EndpointEffectClsid
In Windows 10 and later, the PKEY_FX_KeywordDetector_EndpointEffectClsid property key identifies the keyword detector end point effect (EFX) in place. The driver developer should specify the single supported processing mode that their driver supports for the keyword detector pin.
The INF file property key instruct audio endpoint builder to set the CLSIDs for endpoint APOs into the effects property store. This information is used to build the audio graph that will be used to inform upper level apps what effects are in place.
INF File Sample
An INF file specifies the default format for an audio endpoint device in the add-registry sections for that device. The following INF example shows the strings and add-registry section that loads the APO for an endpoint keyword detector effect into the registry.
