Martin Hamilton 6dd87f6afe ALSA: hda/realtek: ALC269 fixup for Lenovo Yoga Book 9i 13IRU8 audio 
[ Upstream commit 64e0924ed3 ]

The amp/speakers on the Lenovo Yoga Book 9i 13IRU8 laptop aren't
fully powered up, resulting in horrible tinny sound by default.

The kernel has an existing quirk for PCI SSID 0x17aa3843 which
matches this machine and several others. The quirk applies the
ALC287_FIXUP_IDEAPAD_BASS_SPK_AMP fixup, however the fixup does not
work on this machine.

This patch modifies the existing quirk by adding a check for the
subsystem ID 0x17aa3881. If present, ALC287_FIXUP_TAS2781_I2C will
be applied instead of ALC287_FIXUP_IDEAPAD_BASS_SPK_AMP. With this
change the TAS2781 amp is powered up, firmware is downloaded and
recognised by HDA/SOF - i.e. all is good, and we can boogie.

Code is re-used from alc298_fixup_lenovo_c940_duet7(), which fixes a
similar problem with two other Lenovo laptops.

Cross checked against ALSA cardinfo database for potential clashes.
Tested against 6.18.5 kernel built with Arch Linux default options.
Tested in HDA mode and SOF mode.

Note: Possible further work required to address quality of life issues
caused by the firmware's agressive power saving, and to improve ALSA
control mappings.

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 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.
