Hello Hannah, There is no way to add a pin to your driver to receive the usbaudio data. The audio pin does give you a property to inquire the current position of the audio data in bytes received. You can use this information at the app level to resync the captured audio and video.

This device has two interfaces, so for the audio device, the usbaudio.sys driver is loaded. For the video, I have a avstream capture driver. Now, I face video\audio synchronization issues. Is there any way I can add a audio pin to my avstream driver and get the stream from usbaudio.sys? Please give me any suggestions. Thanks.
