Hi, Since the kernel 3.19 mute button stopped working for me, this seems to be the commit: http://git.infradead.org/users/dvhart/linux-platform-drivers-x86.git/commitdiff/9a417ec0c9d1f7af5394333411fc4d98adb8761b Before that (3.18.7) the button worked as well as its led although the state was reset to "unmuted" after suspend. I'm on a Lenovo thinkpad x240 running ubuntu 14.10 with kernel compiled from kernel.org. I'll be glad to help debugging the problem.
