The mute LED on some HP laptops does not work correctly under Linux. The issue is fixed upstream by using the DMI board list along with the ALC245_FIXUP_HP_MUTE_LED_COEFBIT quirk. Since this method requires a DMI board list, every model must be added manually. For example, my Victus 16-s1xxx (Motherboard ID: 8C9C) is supported after I sent this upstream patch.
When building this module, a quirk in patch_realtek.c is populated with the proper fields (see also PKGBUILD).
If the module works out-of-the-box (OOTB), please let me know at issue #1 so we can consider upstreaming the fix. Even if it does not work, your feedback could help us fix the issue together.
