 Posted: Mon May 07, 2018 6:06 pm Post subject: Leds on audio/mic mute buttons |
 |
|
| On my laptop there are buttons with LEDs that mute the audio/microphone. Is it possible to manually light these LEDs in the system? The problem is that the buttons work (I bound them to the required functionality in my WM), and the LEDs do not. To test, when i booted from some live cd with DE, the buttons with LEDs were working. |

Try to enable thinkpad ACPI config in the kernel
| Code: | CONFIG_THINKPAD_ACPI=m
CONFIG_THINKPAD_ACPI_ALSA_SUPPORT=y
# CONFIG_THINKPAD_ACPI_DEBUGFACILITIES is not set
# CONFIG_THINKPAD_ACPI_DEBUG is not set
# CONFIG_THINKPAD_ACPI_UNSAFE_LEDS is not set
CONFIG_THINKPAD_ACPI_VIDEO=y
CONFIG_THINKPAD_ACPI_HOTKEY_POLL=y
|
It works on my thinkpad

Mine not, maybe it's pre configured in DE, but i dont have DE, i think i need somehow to set them up manually.
I looked, but i did not find a solution there. therefore i decided to ask on the forum. |

Do you see the LED lit when you mute the mic/speaker with alsamixer?

No, they did not work, but after rebuilding the kernel and activating everything that is possible in it, they are working now, the problem is solved. Thank you. (Of course the buttons do not work as they should, but this is not a question of this topic.) |
