Find the cause step by step
- Count the black rings on the headset plug (figure below). With 3 rings it has a mic and needs a combo jack or a splitter.
- PC with green and pink jacks: use the TRRS splitter. Laptop with a single jack (headset icon): plug it in directly.
- Click Test microphone above. If the bar doesn’t move, go to System › Sound › Input and pick the pink jack’s mic (sometimes called “Microphone” or “Line In”).
- Still nothing: on a desktop, try the rear jacks; some motherboards ask you to confirm what you plugged in, in the maker’s audio app.
Symptom, cause and fix
| Symptom | Likely cause | What to do |
|---|---|---|
| Works on the phone, not on the PC | 4-contact plug in a separate jack | TRRS splitter adapter |
| With the splitter, still nothing | Windows is using another mic | Pick the mic in Sound › Input |
| Works in the rear jack, not the front | Front panel unplugged | Use the rear jack |
| Mic very quiet | Low input volume | Raise it in Properties › Levels |
Where to find it on your device
- Choose the mic: Settings › System › Sound › Input › choose the right microphone and watch the volume bar move.
- Windows 11: Settings › Privacy & security › Microphone › turn on “Microphone access”, “Let apps access your microphone” and “Let desktop apps access your microphone”.
- Volume and boost: Settings › System › Sound › More sound settings › Recording tab › your mic › Properties › Levels.
Related questions
Which adapter should I buy?
Search for a “TRRS headset splitter” or “3.5 mm headset to dual jack adapter”: a female 4-contact jack that splits into two plugs, one for headphones (green) and one for the mic (pink).
My laptop has one jack. Do I need the adapter?
No, if it’s a combo jack (headset icon). If the icon shows only headphones, the laptop doesn’t take a mic through it.
My headset has two plugs. Where does each go?
The green plug (or headphone icon) goes in the green jack, and the pink one (mic icon) goes in the pink jack.
My Razer, HyperX or other gaming headset mic is not working on PC. Anything different?
USB headsets don’t use the jacks: pick them under Sound › Input and make sure the mute button or flip-to-mute boom isn’t muting them. The maker’s app (Razer Synapse, HyperX NGENUITY) can also mute the mic. Analog ones follow the steps above.
My new headset mic is not working on PC. What should I check first?
The plug type and the input: count the rings, use a splitter on a desktop with separate jacks and pick the headset as input in Sound settings. New USB headsets sometimes take a minute to install the first time.
