On this Lenovo machine, there are two front mics, and both of them are assigned the same name "Mic", but pulseaudio can't support two mics with the same name, as a workaround, we change the location for one of them, then the driver will assign "Front Mic" and "Mic" for them.

Doesn't this Lenovo device need other quirks like hotkey? Just to be sure.
So far, we don't meet hotkey issues on this machine. And this machine is not a laptop, here is the picture of this machine: http://www3.lenovo.com/us/en/workstations-thinkstation-p-series/thinkstation...
