Installing an audio processing object requires the cooperation of the audio
driver author; that is, your APO needs to be listed in their .inf using the
mechanisms listed in the sample.

Subject: [wdmaudiodev] Issues in installing custom sAPO.
Hi,
I am trying to install a Custom sAPO for providing custom audio effects to the
speakers.
For this, I am using sysfx.inf file obtained from location
<WinDDK>\7600.16385.1\src\audio\sysfx\Inf\.
I am stuck with a few issues in this approach :
- I am not able to install it for a USB audio device connected to the system.
Is there any modification required to be done to the sysfx.inf file for this?
- After successful installation of Custom sAPO for a HD Audio Device, if a new
audio device is plugged in, then how can I address it (to install my custom
sAPO for it as well)?
- Also, in some cases audio devices in windows system comes with drivers like
Realtek Sound Manager. Is it possible to apply my sAPO effects to these as well
?
Note that I'm not developing my our own audio driver for high definition (HD)
or USB speaker. My approach here is to just update the existing audio driver
using
sysfx.inf file to apply audio effects.
Regards,
Vinayak S
