#####Copied from askubuntu's Enabling mic mute button and light on Lenovo Thinkpad
There are two possible "hardware" indicators (to show that mute is on or off):
The Power button light (green) will blink to show when mute is on
The Mic mute button light (orange) will be on or off to show mute status (just like in Windows)
Solution 2 requires a patched thinkpad_acpi
kernel module, and is only recommended for advanced users who know what they are doing. This is because the patch is not included by the thinkpad_acpi
developers by default, (See this discussion for more details).
