Support Sound

I’ve just installed Manjaro XFCE on my Lenovo Legion 7 laptop. The speaker is not working but if I switch to my Lenovo headphone it works.

This is the detailed information

ALSA Kernel patch for Realtek ALC287 & CS35L41 amplifiers was added in December
LKML: Lucas Tanure: [PATCH v5 09/10] ALSA: hda/realtek: Add support for Legion 7 16ACHg6 laptop

The patch is only available in kernel v5.17rc1 at the moment
patch_realtek.c - sound/pci/hda/patch_realtek.c - Linux source code (v5.17-rc1) - Bootlin
I would expect the patch to be back-ported to LTS kernels (v5.15,v5.10 etc) in the future, but it is not shown in latest release v5.15.17
