Re: [PATCH] ALSA: hda: cs35l41: Add HP override

20 Dec 2023

Hi,
I recently pushed up some changes that allow you to add laptops into a 
configuration table, these laptops should be added into that instead of 
creating a new function.
I don't have the configuration of some of these laptops right now to be 
able to review it, but hopefully I should be able to obtain them.
Thanks,
Stefan

This adds an override for a series of notebooks using a common config
taken from HP's proprietary Windows driver (csaudioext).
This has been tested on a HP 15-ey0xxxx device (subsystem 103C8A31)
together with another Realtek quirk and the calibration files from the
proprietary driver.
