commit cd14dedf15be432066e63783c63d650f2800cd48 upstream. XPS 9530 has 2 tweeters and 2 subwoofers powered by CS35L41 amplifier, SPI connected. For subwoofers to work, it requires both to enable amplifier support, and to enable output to subwoofers via 0x17 quirk (similalry to XPS 9510/9520).

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.
