Hi, I have a USB video\audio capture device. 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.
