AFAIU, all audio components but the internal microphone are connected to the "Realtek ALC285" codec which is handled by azalia(4). The internal microphone uses the Intel Smart Sound Technology, which needs a dedicated driver. Linux has a driver written by Intel employees, which is around twice as big as azalia. It's unclear how difficult it would be to write a openbsd-ish driver that simply makes the hardware work. Sorry. Meanwhile, if this is for voice calls, I'd suggest either using a phone headset (the x1 probably has a trrs jack) or a comfortable full-duplex usb headset; most work way better than the internal mics/speakers.
