Mute Switch LED not working Hp Omen 15

Support
17

User on a another HP laptop ( Omen 15-en0044ur ) reported a similar problem to kernel developers
214735 – Audio mute led does not work on HP OMEN 15
And a kernel patch was created for this device
https://lkml.org/lkml/2021/11/15/1092

https://elixir.bootlin.com/linux/v5.15.21/source/sound/pci/hda/patch_realtek.c#L8748
SND_PCI_QUIRK(0x103c, 0x8788, “HP OMEN 15”, ALC285_FIXUP_HP_MUTE_LED)

But OMEN Laptop 15-en0xxx has a different subvendor ID code [103c:8787]
(confirmed from hardware scans for similar systems - https://linux-hardware.org/?id=pci:1022-15e3-103c-8787)
so the patch for the mute LED will not be used for this device automatically
and kernel developers did not create a model name for this patch to be used on other devices

I suggest you try using the hda-verb commands suggested in the Bugzilla report to try turning LED on and off
( Ensure package alsa-tools is installed for hda-verb tool )

214735 – Audio mute led does not work on HP OMEN 15
It turns out 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.

If the hda-verb commands work to change the LED, get ALSA information for both LED states

sudo alsa-info.sh

That would be more than sufficient evidence to support a Bugzilla request to kernel developers
to add a quirk for this device to use the same patch - ( SND_PCI_QUIRK(0x103c, 0x8787… )
Or a model option to allow use of the patch - ALC285_FIXUP_HP_MUTE_LED
