How to change the configuration of the LFX/GFX through another standalone application

Hello everyone,

I have just go-through the sAPO sample in WDK 5384 (audio/sysfx)

In this sample, in SwapPropPage.cpp, it use m_pAudioFXExtParams->pFxProperties to retierive the self-defined the LFX/GFX parameter, like PKEY_Endpoint_Enable_Channel_Swap_LFX

and m_pAudioFXExtParams is passing by external "Control Pannel" application.

// Keep audio FX extension parameters passed by the control panel
pthis->m_pAudioFXExtParams = (AudioFXExtensionParams*)pSheetDesc->lParam;

I wanna know whether there is some other method to create that parameter in a standalone application and use it to control the LFX/GFX user-defined parameter.

Does anybody have the experience on this? Thanks in advance

Thanks.

Yang
