The DualSense controller complies with v1.0 of the USB Audio Class spec (UAC1), hence it cannot advertise any jack detection capability. However, this feature can be implemented in the generic USB audio driver via quirks, i.e. by configuring an input handler to receive hotplug events from the HID driver. When operating in USB mode, register a dedicated input device for the audio jack and use it to report all headphone and headset mic insert events.
