Do you know how to make an INF file for an APO paired with the USB or HD Audio class drivers?

There is no overview and little documentation on how to create INF files for audio devices which extend the HD Audio class driver using APOs and filter drivers. There is zero documentation on how to extend the USB class driver.

Optimal Sound has the experience to create powerful INF files which can leverage both HD Audio and USB Audio class drivers.

The Optimal APO Framework includes support for INF files. We can also provide customized training sessions which provides detailed information on the subject.
