I had the same problem. I took the motherboard out and sonicated it in about 90% isopropyll alcohol. I think 70% rubbing alcohol from drug store would work too. I only used enough in glass to cover the microphone. I let it dry for a few hours and it was working again. I wouldn't go poking the tiny hole with a needle, as I think that would dammage it. Next time you use glue, take out the motherboard first. I learned my lesson.
