Windows Audio Processing Objects installation and Registrstion

Hello everyone,

I am working on Audio Processing Objects and build sysvad’s SwapAPO project, SwapAPO.dll got generated. I am trying to attach the SwapAPO to the Realtek(R) Audio device by wroting component and extension inf files.

Observations:

  1. I successfully bind SwapAPO to the Realtek Hardware.
  2. In the Device Manager “Audio Processing Objects” got created and :Realtek(R) Audio name got changed to “Swap APO Realtek Speaker” as i mentioned in the extension inf.
  3. In the Audacity, I chosen “Swap APO Realtek Speaker” as Playback device and played a .wav audio file.

Result:
The channels are not swapped!!

The attached are the screenshots of my observstions.

Did I missed anything in the registration process? Please let me know.
