Hello, I am a newer for driver development. I am developing an AVStream minidriver for USB audio device (win7 system).
Now, I can install my device (please refer to the device.png), but I cannot find my device in sound management (please refer to the sound.png). The following is the filter and pin description. Could you help us to check them. Thanks.
