Problem description: The CSC3551 chipset does not get initialized correctly in aforementioned laptop models. While the rest of snd-hda-intel recognizes the hardware correctly, the smart amplifier does not get initialized so that the built-in loudspeakers do not work. The patches originate from discussions and tests under https://github.com/xoocoon/hp-15-ew0xxx-snd-fix.

Unresolved issues: The LED indicating muted sound on the laptop keyboard does not work. The same holds for the LED indicating a deactivated microphone. These issues are not addressed by the patches.
