The Sony DualSense wireless controller (PS5) features an internal mono speaker, but it also provides a 3.5mm jack socket for headphone output and headset microphone input. Since this is a UAC1 device, it doesn't advertise any jack detection capability. However, the controller is able to report HP & MIC insert events via HID, i.e. through a dedicated input device managed by the hid-playstation driver. Add a quirk to create the jack controls for headphone and headset mic, respectively, and setup an input handler for each of them in order to intercept the related hotplug events.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
