Toggle Mic Mute Lenovo X1 Carbon

Post by Tortugaverde » Wed Mar 08, 2017 9:57 am

I have a 1st Gen Lenovo X1 Carbon. Switched from Ubuntu to Linux Mint 18 'Sarah' "Xfce 64-bit" and found my microphone mute button was not working. Everything else is locked-in.

I did some research and found that I can go into PulseAudio Volume Control, select "Input Devices" and toggle "Mute Audio" there where Port: = Internal Microphone. Interestingly, the indicator light on my keyboard microphone mute button toggles on when I mute via Volume Control (via mouse click in the GUI). Pressing the physical button on the keyboard does nothing either way.

A little more research and I found an Ubuntu thread that helped me to start mapping the keys. I opened Terminal and entered the command acpi_listen This gave the following output:
button/f20 F20 00000080 00000000 K

Thus the button is active and acting like a Fkey.

So how do I map a keyboard shortcut to my physical microphone toggle mute on/off button? What would the command be that toggles the mute button in PulseAudio Volume Control - Input Devices - toggle mute for microphone? And how do I set the shortcut to the F20 key on my keyboard to accomplish this?

Thanks! :D

I also have the same issue on a Lenovo T450s. Everything else works perfectly.
