This are very cheap and adapt USB-C to Jack . I've tried to find how this works, but nothing. Someone suppose that are just direct connection from Jack pins to USB Audio Mode pins and some that there's electronics in it.
Someone have more infos or have tried something with them?
It says it's for a Samsung phone, not an Arduino. The Arduino doesn't have USB audio drivers. And the basic Arduino USB port is configured as a device, not a controller.
