== General ==
Some Thinkpads come with a Microphone Mute Button possibly with an led.

The Microphone Mute Button on the T410 and T410s does not work on Ubuntu 10.10 and Ubuntu 11.04.

== Workaround using acpid ==
Pressing the mic mute botton will generate a acpi event
$ apci_listen
ibm/hotkey HKEY 00000080 0000101b
add a acpid rule to handle this event in {{patch|/etc/acpi/events/lenovo-mutemic}}:
event=ibm/hotkey HKEY 00000080 0000101b
action=/etc/acpi/lenovo-mutemic.sh
the script ({{path|/etc/acpi/lenovo-mutemic.sh} to toggle the mice look like this:
<pre>
#!/bin/bash

led="/sys/devices/platform/thinkpad_acpi/leds/tpacpi::micmute/brightness"
user=$(who | awk '/0\.0/{print $1; exit;}')
[[ -z $user ]] && user=root
if [[ $(amixer sget Capture) == *"[on]"* ]]; then
logger "Microphone is now muted (for $user) $USER"
amixer sset Capture nocap
[[ -f $led ]] && echo 1 > $led
sudo -u $user DISPLAY=":0.0" notify-send -i microphone-sensitivity-muted-symbolic "Microphone" "Microphone is now <b>MUTED</b>"
