Sorry for the delay.

Yes, I have tried plugging both my mic and speaker in all three
By plugging in my mic into speaker, it also shows as plugged.
So my mic is ok and not the problem.

At this point, I suspect that this motherboard is also defective.
This one was not my first choice, that one was defective.
What a crappy two weeks for parts!
