Hardware: HP laptop models HP Envy x360 15-ew0xxx (with codec Realtek ALC245 and Cirrus Logic Smart Amplifier chipset CSC3551) vendor_id: 0x10ec0245, subsystem_id: 0x103c8a29, revision_id:0x100001

Kernel version: 6.2+

Output of alsa-info.sh attached (with the patch applied)

Patch repository for reference: https://github.com/xoocoon/hp-15-ew0xxx-snd-fix

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 patch is confirmed to work by another user owning said laptop model.

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.
