Top 16 Fixes for Discord Mic Not Working on PC and Mobile

Discord Mic Not Working

Are others unable to hear you when you speak in the Discord app? There could be an issue with the microphone settings either in the app or on your device. Let’s check various ways to fix the problem of the Discord mic not working on PC, Android, and iPhones.

1. Restart Device

Be it the computer or the mobile phone, you should restart the concerned device to fix the Discord microphone. A single restart will often fix a temporary issue that could be hampering the Discord mic.

2. Reconnect External Microphone

If you are using an external microphone, you should unplug and replug it. Also, make sure that the USB port or the 3.5 mm jack on your device is clean. You can try blowing some air through it to remove any dust particles.

Similarly, if you are using Bluetooth headphones like AirPods, disconnect and reconnect them with your mobile or computer.

3. Unmute Yourself (PC)

You might have accidentally muted yourself in the Discord PC app and that’s why people might not hear you. You will see a red slash (/) on the microphone icon when the mic is muted. To unmute yourself, click on the “Microphone” icon next to your username at the bottom left.

9. Check Input Mode

Discord offers two input modes: Voice Activity and Push to Talk. By default, the Voice Activity mode is selected, which means the microphone is actively listening for voice activity and you can speak into it whenever you want. However, if Push to Talk is selected, unless you press the relevant button when you want to speak, your voice isn’t captured. Consequently, you may chalk this down to a faulty microphone.

Check Input Mode on PC

  1. Open “Discord Settings → Voice & Video.”
  2. If “Push to Talk” is selected under the input mode, set a shortcut using the “Record Keybind” button, then lower “Push to Talk Release Delay” using its slider.

Check Input Mode on Mobile

  1. Tap on the “Account” icon and go to “Voice.”
  1. If the “Input Mode” says “Push to Talk,” open any Discord channel where you want to speak and press the “Push to Talk” button whenever you want to say something.
