USB Setup Requests for UAC Class events

AlNa_1728166 Sep 10, 2019 3:37 PM

I’m trying to add audio control features to my FX3 based UVC system to control volume and mute. My system currently supports audio but does not have any audio descriptor to control volume and mute options. I’m modifying the descriptor to support that, however I don’t see a way in API document to get and audio events.

Does anyone know how to handle audio set up commands?
