Cracking noises have been reported on the built-in speaker for certain Bullseye platforms, when volume is > 80%. This issue is caused by the specific combination of Codec and AMP in this platform, and cannot be fixed by the AMP, so indead must be fixed at codec level, by adding attenuation to the volume. Tested on DELL Inspiron-3505, DELL Inspiron-3501, DELL Inspiron-3500 Signed-off-by: Stefan Binding <sbinding@opensource.cirrus.com> Signed-off-by: Vitaly Rodionov <vitalyr@opensource.cirrus.com> BugLink: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1924997 Reported-and-tested-by: You-Sheng Yang <vicamo.yang@canonical.com> Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20210426163749.196153-3-vitalyr@opensource.cirrus.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
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.
