commit 8eedd3a70a70f51fa963f3ad7fa97afd0c75bd44 upstream. It was reported that the headphone output on ASUS UX430UA (SSID 1043:1740) with ALC295 codec is silent while the speaker works. After the investigation, it turned out that the DAC assignment has to be fixed on this machine; unlike others, it expects DAC 0x02 to be assigned to the speaker pin 0x07 while DAC 0x03 to headphone pin 0x21. This patch provides a fixup for the fixed DAC/pin mapping for this device.

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.
