What is your firmware version? Is it the latest? Yes it is the latest (6EET49WW (3.09 )). It's is for all X301 firmware versions. Though this work around seems to be in all Thinkpad Bioses. If you go into the kernel in drivers/acpi/blacklist.c you can see the current Thinkpads that it is there for now. For the X/T 61 & T 400/500 there is not little light to show the mute is on. It seems having OSI=Linux actually creates a better user experience for these laptops. Same for the X200 (which I had planned a patch for). But now all new Thinkpads out of Lenovo use the new keyboard format and the mute now has a little light. Can see this with the T410 and the other thinkpads.
