Can't Mute or Unmute in Teams – Fix

You're trying to chime in, but the mute button is greyed out or won't respond to your clicks. This is often a "Human Interface Device" (HID) driver conflict. Againly fixes this automatically by re-starting the HID listener service that connects your mouse/keyboard to the Teams app.

Why this happens

  • Headset Sync Error: Your Jabra or Logitech headset has a local mute that has confused the Teams software.
  • App Lag: Teams is using 100% of your CPU, causing the UI buttons to become unresponsive.
  • Meeting Permissions: The organizer has "Hard Muted" all participants and you missed the notification.

Fix it manually

  1. Keyboard Shortcut: Try Ctrl + Shift + M to toggle mute.
  2. Reconnect Audio: Click the arrow next to the mute button, switch to "System Speakers," then switch back to your headset.
  3. Task Manager Restart: Kill the "Teams" process and re-join the meeting.

Fix it automatically with Againly

Againly clears the input lag and resets your headset's communication bridge to the Teams server in under 2 minutes.
