Method 12: Check the Jack

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.

So, choose a 4-pin 3.5 mm TRRS or Tip Ring Ring Sleeve audio jack instead of a 3-pin TRS or Tip Ring Sleeve audio jack.


First, check the jack to find out which type of jack you are using.

Now, look at the front panel audio connectors for the mic and headphones, which look just the same but have different markings for the headphone and the mic.

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:

Typically, this type of mic may need a separate type of connectivity and arrangement 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.

Method 13: Uninstall Audio Inputs and Outputs

The ‘Audio inputs and output’ setting may be incorrect and therefore, your microphone may not be detected.

In that case, it is better to try updating it, and if the mic still does not work then uninstall it to resolve the issue.

Steps to Fix a PC Not Detecting Headphones Jack

The PC may sometimes not detect the headphone set due to a faulty port where you have inserted the jack. Fixing this issue is quite simple.

Method 16: Check the Audio Source

Assuming that your jack is not damaged and it has the right number of pins, and the volume is not muted, it may not work sometimes because the slots on the PC may be faulty.

So, changing and trying a different slot and source may resolve the issue.
