Greetings everyone I am not sure if this is the right place to ask, but I don't know where else to look for help. I have a laptop (HP Omen 15 2020 amd) which has a mute button (Fn + F5) which works great, however, the LED indicator on it doesn't light up. With the help of this article https://asus-linux.org/blog/sound-2021-01-11/ I managed to figure out that I can trigger the LED with the following command:
sudo hda-verb /dev/snd/hwC1D0 0x20 0x500 0x0B && sudo hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7778 And disable it with sudo hda-verb /dev/snd/hwC1D0 0x20 0x500 0x0B && sudo hda-verb /dev/snd/hwC1D0 0x20 0x400 0x777 I think that a fix should be added to patch_realtek.c https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/pci/hda/patch_realtek.c (to change those values when mute button is pressed) but this requires knowledge of C and kernel stuff. I don't have much experience with those so I would be very grateful if anyone could help me. I have also filed a kernel bug report https://bugzilla.kernel.org/show_bug.cgi?id=214735 (with some useful attachments) but nobody responded there.
Thanks in advance
