From e1c24d545b8d0f4f04e01258f1ac5d2934c6a08d Mon Sep 17 00:00:00 2001 From: Cristian Ciocaltea Date: Wed, 25 Jun 2025 00:56:55 +0300 Subject: [PATCH] HID: playstation: Support DualSense audio jack event reporting 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.
