Public bug reported:
I took a fresh install of Ubuntu 14.04 on Lenovo Thinkpad T420 with Nvidia NVS
Mute microphone button works fine.
Also muting in the sound settings switches the led indicator on the button on
and off as expected.
I installed nvidia driver 331 required by CUDA toolkit.
Restart.
System works fine except the microphone mute button.
However, muting the mic in the sound settings dialog switches the led indicator
correctly again.
It looks like only the button is not sending any event to the sound settings.
Switching to nouveau driver solves the problem but CUDA will not work.
