The correct line to put in /etc/modprobe.d/alsa-base.conf should be: options snd-hda-intel model=mute-led-gpio Please correct it and try again.
Please also upload the output from alsa-info (run alsa-info in a terminal). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1811254 Title: HP ProBook 470 G5, LED's in Hotkeys f5, f8 and f11 without function Status in linux package in Ubuntu: Confirmed Bug description: Notebook: HP ProBook 470 G5 (3KZ03EA) Distro: Linux Mint 19.1 Tessa Desktop: Cinnamon 4.0.8 Kernel: 4.15.0-43-generic x86_64 bits: 64 The functions of all hotkeys are given, but the LED's in the [f5] Speaker-mute, [f8] Micro-mute and [f11] Wireless on/off Buttons do not show the status. Disturbing is also the LED in [f11] permanently lit. This is my first bug report to launchpad and I ask for leniency and troubleshooting support. I created 12 logs, unfortunately the upload did not work at once: acpi_listen.txt apt-cache-policy dmesg.log lsb_release lsinput.log lspci-vnvn.log rfkill_list.txt udev-db.txt version.log xev keypress test.txt xkbcomp.txt xkbmap.txt Previous attempts: My on-board search for other HP ProBook Hotkey LED-issues led me to this bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1705586 but the solution to the file: /etc/modprobe.d/alsa-base.conf to supplement the entry: options snd-hda-intel mode = mute-led-gpio did not lead to the solution here. Presumably, the failure results from a different ubuntu-version and/or a another kernel.
