Your schematic is not saying more about your problems.

If you think the problem is in your Mic then you need to change the Mic (I don't know it's dynamic or condenser or etc). Sometime we suffer from wire breaking problem very near the 3.5mm plug shown in schematic due to continuous bending wire. Check continuity of the wire (Mic to plug), if it's fine, replace another Mic and see.

Hi Ron,
I think it would record just a single channel ( just L or R) if he is using stereo recording software. Because one of the channel (ring of the plug) has been sorted to ground.

The mics I use have the shield on the sleeve.
Then the two wires with signal are on the tip and ring.

I was thinking 1/4" jacks, because that is what I use.
Even the little "boom box" mics are wired "mono".
But I can see if the input is stereo how they should be wired like in post #1.

My cheap Chinese headset (Earpiece with Mic) for computer has same wiring as post #1. When I record audio in 'Adobe Audition' or 'Cool Edit Pro' sound editing softwares, I get L and R both audio. Sure, I get same audio (captured from Mic1) in L and same audio in R. If I wired as you did, then I can see the one channel has no audio, so that I just can listen audio in my one ear. That is how I knew how stereo effect heppens!

From post #1 we don't know what mic.
If it a PC sound card thing I agree with you. Or stereo mic. Probably stereo. ??
BUT
If it is anything not PC then that diagram is wrong.

In professional wiring the sleeve and ring can be shorted together.
Because we don't know............we don't know.

the desktop headset with mic can only record mono on both channels(paralleled)while the headphones are real stereo.
Thus perhaps except for line in jack, there is no stereo for mic.We can perhaps improvise stereo mic set up by making as shown by Ron.

A microphone input is for a single mono mic, not for a stereo mic. A stereo mic on a headset is made only for people who have two heads.
A headset with a mic has 4 connections, not just three: mic, left ear, right ear and ground.

Nice Joke, a dual headed person. Audio guru's imagination !
