The mute and volume buttons often don't work and I must manually mute or change the volume through the operating system. Once I do that then they start working again. Not sure about the mic button because I don't use it. This has happened since I got my X220 and the updates have not fixed the issue.

Yeah just asking since I have the same issue, but it only turns up when Im on youtube (or maybe other video streamings) when I click away from the browser the VOL/MUTE works again.

i have the same issue, and what i noticed is that, some program takes over the volume buttons fuctions and wont let other programs use it. ie. AIMP2 player, so in order to make it work again i have to close AIMP2, which is annoying.
and some program sort of take over the buttons temporary, or only when the program is in the foreground so i just click at the taskbar once, and the buttons work again.
however i have to say lately i dont get this problem as often as lets say 6 weeks ago. maybe some of the updates fixed that or... i just dont notice anymore. or i dont pay attention to it anymore.

I've noticed it as well when a VirtualBox window is focused (not in fullscreen mode).
I've also another issue that the Volume and Brightness indicators are cut that shows only half portion of the range. It usually happens after restoration from hibernation. See screenshot here http://forums.lenovo.com/t5/ThinkVantage-Technologies/Bug-On-Screen-Display-level-indicators-sometim...
