Export the DAC functionality to mix left + right together and then output the same (mixed) signal on both outputs. Various (x86) tablets with an ES8316 codec use a single speaker connected between the headhpone LOUT and ROUT pins, expecting the output to be in a mono differential mode. Presumably this is done to use the power of both the left and right outputs to allow the speaker to be louder. The ES8316 codec does not have a differential output mode, but we can emulate this by making both channels output the same through the mono mix switch, combined with setting the Playback Polarity control to "R Invert", which applias a 180 degrees phase inversion to the right channel.

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.
