[ Upstream commit c062166995c9e57d5cd508b332898f79da319802 ] Realtek codec on HP Envy laptop series are heavily modified by vendor. Therefore, need intervention to make it work properly. The patch fixes: - B&O soundbar speakers (between lid and keyboard) activation - Enable LED on mute button - Add missing process coefficient which affects the output amplifier - Volume control synchronization between B&O soundbar and side speakers - Unmute headset output on several HP Envy models - Auto-enable headset mic when plugged This patch was tested on HP Envy x360 13-AR0107AU with Realtek ALC285 The only unsolved problem is output amplifier of all built-in speakers is too weak, which causes volume of built-in speakers cannot be loud as vendor's proprietary driver due to missing _DSD parameter in the firmware. The solution is currently on research. Expected to has another patch in the future. Potential fix to related issues, need test before close those issues: - https://bugzilla.kernel.org/show_bug.cgi?id=189331 - https://bugzilla.kernel.org/show_bug.cgi?id=216632 - https://bugzilla.kernel.org/show_bug.cgi?id=216311 - https://bugzilla.kernel.org/show_bug.cgi?id=213507 Signed-off-by: Athaariq Ardhiansyah <foss@athaariq.my.id> Message-ID: <20240310140249.3695-1-foss@athaariq.my.id> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Sasha Levin <sashal@kernel.org> |

README
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.
