Fix: Discord microphone not working

Discord microphone problems are often caused by the wrong input device, input sensitivity, push-to-talk, permissions, noise suppression, or headset/Bluetooth issues.

Quick answer

Open Discord Voice & Video settings, choose the correct input device, test the mic, and check whether push-to-talk or input sensitivity is blocking you.

Important warning

Noise suppression and input sensitivity can make Discord ignore quiet voices even when the microphone technically works.

Try this

  1. 1 Open Discord User Settings → Voice & Video.
  2. 2 Choose the correct Input Device.
  3. 3 Use Mic Test and watch whether Discord detects your voice.
  4. 4 Check whether Push to Talk is enabled.
  5. 5 Reset input sensitivity or turn off automatic sensitivity temporarily.
  6. 6 Disable noise suppression temporarily for testing.
  7. 7 Check system microphone permissions.
  8. 8 Restart Discord.
  9. 9 Unplug and reconnect your headset or USB microphone.

Common causes

FAQ

Why is my mic not working in Discord?

Discord may be using the wrong input device, push-to-talk may be enabled, input sensitivity may be too high, or microphone permission may be blocked.

What is input sensitivity in Discord?

Input sensitivity controls how loud your voice must be before Discord transmits it.

Can noise suppression block my voice?

Yes. Noise suppression can sometimes treat quiet or unusual voices as background noise.
