[ Upstream commit da94692001ea45ffa1f5e9f17ecdef7aecd90c27 ] The 2021-model XPS 15 appears to use the same 4-speakers-on-ALC289 audio setup as the Precision models, so requires the same quirk to enable woofer output. Tested on my own 9510.

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.
