Mute LED light is not working on my HP laptop

I have a laptop, HP Pavilion Gaming Laptop 15z-ec0. the laptop has a mute LED light on the F6 key. It is supposed to light up when the sound is muted.  However, this does not light up when muted. I have tried various models under snd_hda_intel but nothing has worked.

The sound card info is:

/proc/asound/card0/codec#0:Codec: Nvidia GPU 94 HDMI/DP
/proc/asound/card1/codec#0:Codec: Realtek ALC285

The research I've done indicates that:

 sudo hda-verb /dev/snd/hwC1D0 0x20 0x500 0x0B && sudo hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7778

enables this LED and

sudo hda-verb /dev/snd/hwC1D0 0x20 0x500 0x0B && sudo hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7774

disables the LED.

This bug is similar to this bug: https://bugzilla.kernel.org/show_bug.cgi?id=214735

I believe there may be a patch already for other HP models, but something needs to be put into the kernel to tell them to trigger this patch.

I would greatly appreciate it if you would be able to apply the patch to my model so that my LED light would work properly. Thanks!
