Hey guys I was wondering if there was any software to run the microphone in my laptop that works with Linux?
The microphone should work by default through Alsamixer / PulseAudio (default audio engine on Linux). I have a Lenovo Yoga 13 and the microphone works. It's just a matter of software using it for recording and whatnot. You should be able to just use Audacity to record.
I don't have the X1 but several other (current and older) Thinkpads and the mic always worked.
Did you probably deacitvate it in the BIOS/UEFI?
