Hey everyone!

I want to use the UAC Gadget function on the Genio 1200.  
How can I enable it? Any recommendations for this?

Thanks a bunch!

Please follow the steps: (tested on kernel v6.6)

1. Enable UAC related kernel option

2. Add UAC config to USB gadget via console (UART/SSH) on EVK

3. Connect USB-0 to Windows PC, a USB audio device “Source/Sink” should be registered.

4. Play audio on EVK, receive(hear) on PC

5. Play audio on PC, record on EVK
