Mic muted without realizing

You're talking but no one hears you. This can happen mid-stream without warning.

Few things are worse than realizing 20 minutes into a stream that your mic has been muted. Here's why it happens and how to prevent it.

Common causes

1. Push-to-talk accidentally enabled

Push-to-talk might be enabled without you realizing it, or it was configured in a scene you switched to.

  1. Right-click your mic in the Audio Mixer
  2. Select Properties
  3. Check if Push-to-talk is enabled. Disable if you don't use it
  4. Also check Settings → Hotkeys for any push-to-talk bindings

2. Hotkey pressed by accident

OBS hotkeys can conflict with game controls.

  1. Go to Settings → Hotkeys
  2. Find mute/unmute bindings for your mic source
  3. Check if the key overlaps with something you press during gameplay
  4. Use a modifier key combo like Ctrl+Shift+M instead of single keys

3. Windows privacy settings

Windows can revoke microphone access from apps, especially after updates.

  1. Open Settings → Privacy & Security → Microphone
  2. Make sure "Let apps access your microphone" is On
  3. Scroll down and verify OBS is allowed

4. Mic physically muted

Many microphones and headsets have hardware mute buttons.

5. Audio interface software

If you use an audio interface (Focusrite, GoXLR, etc.), it has its own mixer.

6. OBS source disabled in scene

The mic source might not be active in your current scene.

Prevention

Add a visual indicator

Add an on-screen element that shows when your mic is active:

  1. Add an Audio Meter source to your scene
  2. Position it somewhere visible to you (not necessarily viewers)
  3. If it's not moving when you talk, something's wrong

Use a mic with a visible LED

Many mics have LEDs that indicate recording or mute status. Glance at it periodically.

Avoid single-key mute bindings

Never bind mute to keys you might press during gameplay. Use multi-key combos or a dedicated stream deck.

Test at the start of every stream

Say something at the start and confirm in chat that viewers can hear you. Make it a habit.
