Get Support For Your Laptop Model - username227/MuteLED GitHub Wiki
Follow these instructions to see if support for your laptop model can easily be added to the script.
Different HP laptops have different keymaps which identify the LED light that turns on when the system is muted. The commands in the readme are the default commands, as the feedback from the majority of users is that these commands work. However, there are some users who have reported different keymap commands that are needed. If one of the following sets of commands works for you, then the script may not work automatically for you until your model information is added to the script.
Before you run these commands, follow the instructions in the readme to get your audio card number, and be sure to replace cardnumber with hwC0D0, hwC1D0, or hwC2D0, as appropriate.
The commands are:
| Action | Command |
|---|---|
| To turn on the mute LED: | sudo hda-verb /dev/snd/cardnumber 0x20 0x500 0x0b && sudo hda-verb /dev/snd/cardnumber 0x20 0x400 0x8 |
| To turn off the mute LED: | sudo hda-verb /dev/snd/cardnumber 0x20 0x500 0x0b && sudo hda-verb /dev/snd/cardnumber 0x20 0x400 0x0 |
| Action | Command |
|---|---|
| To turn on the mute LED: | sudo hda-verb /dev/snd/hwC1D0 0x20 0x500 0x7 && sudo hda-verb /dev/snd/hwC1D0 0x20 0x400 0x1 |
| To turn off the mute LED: | sudo hda-verb /dev/snd/hwC1D0 0x20 0x500 0x7 && sudo hda-verb /dev/snd/hwC1D0 0x20 0x400 0x0 |
If any of these sets of commands works, but the module does not work for you as written, please open a new issue using the Request LED Support issue template, providing all pertinent information, and I will try to add support for your model as quickly as possible.
If you discover that your mute LED light works with different commands, please open a new issue or report the details in Issue #1. These commands can also be added as an option in the script to get it to work for your model.
