Now, if the above solution did not work, there may be an issue with the jack and you may need to rectify it.

Did you know that a 3.5 mm jack comes in two forms, namely, 3-pin and 4-pin? Obviously, if you use a 3-pin jack, your PC will not detect the mic but the sound may be fine.

If you connect a 3.5 mm 4-pin audio jack in the headset slot, you will hear sound, but the mic will not work.

In that case, you will need to use a special type of cable that comes with a splitter and two different connectors marked for the mic and headset.

Now, simply plug in the connectors into the right slots according to the marks and it will resolve the issue.

In some rare cases, users may use a separate microphone with their PCs like this:

If you have a new PC, such as a new All-in-One computer system, it will typically come with a single 4-pin TRRS 3.5 mm jack as shown below:

So, if you use a 3-pin connection, the mic will not work. Therefore, you will need a different jack for the adapter to recognize the microphone. You will need to use a 3-pin to 4-pin adapter like this one.
