Hi there,
I move SwapApo from render device recoding device, and it is loaded in one
NB. But on another NB, it isn't loaded when recording.
The recording device is opened in recording page which shows all available
recording device.
Would you have any idea about:
1. what should be checked about the apo not loading?
2. If an APO doesn't work properly, audiodg will disable and ban it,
according to my experience of developing apo in vista. Does this operation
remain the same in Win10, and how can I restore the APO to be called by audiodg?
Best regards.
Wayne Wang
