Headphones "Mic" Not Working on PC

4.5

You can hear audio fine, but your computer doesn't detect the microphone on your headset.

Symptoms
  • No mic input
  • Internal mic used instead
  • Error message
Possible Causes
  • Privacy settings
  • Wrong input device selected
  • Splitter cable needed

Step-by-Step Fix

1

Check Privacy Settings

Settings > Privacy > Microphone > Allow apps to access your microphone.

2

Set as Default Device

Sound Control Panel > Recording > Right-click Headset > Set as Default.

3

Use a Y-Splitter

If your PC has separate green/pink jacks, you need an adapter for a single-plug headset.

When to See a Technician

Windows often defaults to the laptop's built-in mic even when a headset is plugged in.
