This is supposed to work, and it works fine on my X220.  What Thinkpad
do you have, and what distro are you running?

Can you run alsamixer (with software_mute=1) and watch the controls to
see what changes when you press mute?  IIRC, when the master volume
goes to 0 or is muted, the magic ALSA hooks will tell thinkpad_acpi so
that thinkpad_acpi can adjust the LED.
