Can you plug in a Lavalier mic which has a TRRS connection on it directly to your motherboard analog input or does it need a adapter for it to work correctly as a mic?

Could you be more specific about the mic you're trying to use. I wouldn't expect any mic to have a TRRS (4 pole) connector, more likely a TRS connector (3 pole). If it's a TRS then yes you can plug it into a mic input on a motherboard. If it's a TRRS then you might need a TRRS splitter, which can then be plugged into the motherboard. If it's a laptop then you might not need the splitter as they often have 4 pole combined mic/headphone sockets, but check against it's specs.

Lots of cheap mics available on Amazon in the States have a TRRS connector. Their wiring scheme is.... dubious, at best.

Well, considering electret microphone elements are 2 pole... They're bridging pin 2 and 3 with a diode, but what the heck is that 4th for?
