Recently we enabled a HP AIO machine, we found the mic on the machine couldn't record any sound and it couldn't detect plugging and unplugging as well. Through debugging we found the mic is set to manual detect mode, after setting it to auto detect mode, it could detect plugging and unplugging and could record sound.

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 Restructured Text 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.
