🔎 What This Guide Covers:

This guide helps you fix issues when you can’t hear any sound from your computer—whether it’s system sounds, music, or audio during a Microsoft Teams call. It's especially helpful if you’re using Bluetooth headphones but nothing plays, or you're unsure which device is set as the speaker/mic.

Use this guide when:

• You don’t hear anything from your Bluetooth or wired headphones.
• Microsoft Teams says you're connected but no one can hear you (or you can't hear them).
• The wrong device is selected for sound.

✅ Steps to Fix the Issue

🔊 Step 1: Make Sure Your Headphones Are Powered On

• Press and hold the Power or Bluetooth button on your headphones.
• You should hear a voice prompt or see an LED light flashing.
• If nothing happens, charge the headphones first.

📶 Step 2: Check That Your Headphones Are Connected via Bluetooth

1. Go to Settings → Bluetooth & devices 

2. Ensure Bluetooth is ON

3. Look under Audio
• If not connected, click on your headphones and select Connect

• If not visible, click Add device → Bluetooth → Select your headphones from the list

🔁 Step 3: Set Your Audio Output and Input Device

Sometimes your PC is sending audio to the wrong place.

1. Click the sound icon on the bottom-right corner of the taskbar

   2. Click the drop-down next to the volume slider

3. Select your Bluetooth headphones as the Output device

To check input (microphone):

1. Go to Settings → System → Sound

2. Under Input, make sure your headphones’ mic is selected

💬 Step 4: Check Your Audio Settings in Microsoft Teams

If the issue is in a Teams meeting:

1. Open Teams, click the three dots next to your profile photo > Settings
2.                    
3. Go to Devices
4. Under Audio devices, ensure:
• Speaker is set to your Bluetooth headphones
• Microphone is also your headphones, if they have a mic
5. Click Make a test call to confirm it's working

🔁 Step 5: Restart Audio Services (if sound still doesn’t work)

Sometimes restarting your PC can help reset the audio system.

• Save your work and restart the computer.
• After restart, reconnect your headphones as in Step 2.

📝 If It Still Doesn’t Work:

• Try using another pair of headphones to rule out hardware issues.
• Disconnect and "Forget" the Bluetooth device, then reconnect it.
• Escalate to IT through a ticket with a screenshot of your current sound settings and what you’ve tried.
