+## audio led buttons
+
+On some ThinkPad models, audio led buttons can be broken and desynchronized
+on linux `5.15.x`.
+
+A quick workaround is to catch the key press events (in your dwm configuration,
+i3, sway, etc ...) and force the synchronization of the leds.
+
+For the microphone:
+
+```
+$ pactl get-source-mute @DEFAULT_SOURCE@ | grep no >/dev/null 2>&1
+$ echo "${?}" > /sys/class/leds/platform::micmute/brightness
+```
+
+For the audio sink:
+
+```
+$ pactl get-sink-mute @DEFAULT_SINK@ | grep no >/dev/null 2>&1
+$ echo "${?}" > /sys/class/leds/platform::mute/brightness
+```

+See my [dotfiles](https://git.rgoncalves.se/dots/tree/.bin/ag-audio) and
+[the related pipewire issue](https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1849).
