Skype Audio and Video Not Working? Here's How to Fix It

Few things are more frustrating than jumping on an important Skype call only to find that nobody can hear you — or your camera shows a black screen. These issues are common, but they're almost always fixable. This guide covers the most effective troubleshooting steps for both audio and video problems.

Diagnosing the Problem First

Before diving into fixes, use Skype's built-in audio test to narrow down the issue:

  1. Search for Echo / Sound Test Service in your Skype contacts.
  2. Start a call — it will play a tone and record your voice, then play it back.
  3. If you can hear the tone but not your voice, your microphone is the problem.
  4. If you can't hear anything, your speakers or audio output is the issue.

Fixing Skype Audio Problems

1. Check Skype's Audio Settings

  1. Go to Settings → Audio & Video.
  2. Under Microphone, make sure the correct input device is selected from the dropdown.
  3. Under Speakers, verify the correct output device is chosen.
  4. Click Test audio to confirm speakers are working.

2. Check Windows / macOS Permissions

Windows: Go to Settings → Privacy & Security → Microphone and confirm that Skype has permission to use the microphone.

macOS: Go to System Settings → Privacy & Security → Microphone and toggle Skype on.

3. Check System Volume and Mute Status

This sounds obvious, but it's surprisingly common — check that:

  • Your system volume isn't muted or set too low.
  • The Skype in-call mute button (microphone icon) isn't active.
  • Your headset or speakers are properly plugged in and powered on.

4. Update Your Audio Drivers

Outdated drivers can cause Skype to lose access to your audio hardware. On Windows, open Device Manager, expand Sound, video and game controllers, right-click your audio device, and select Update driver.

5. Disable Exclusive Mode for Your Microphone

On Windows, some applications claim exclusive access to audio devices. To disable this:

  1. Right-click the speaker icon in the taskbar and select Open Sound settings.
  2. Under Input, click your microphone and go to Device properties → Additional device properties.
  3. On the Advanced tab, uncheck Allow applications to take exclusive control of this device.

Fixing Skype Video Problems

1. Check Camera Selection in Skype

Go to Settings → Audio & Video and make sure your webcam is selected under Camera. If you see a black preview or "No camera found," the issue is with detection.

2. Check App Permissions for Camera Access

Just like microphone permissions, your OS must grant Skype camera access:

  • Windows 11: Settings → Privacy & Security → Camera → Enable for Skype.
  • macOS: System Settings → Privacy & Security → Camera → Toggle Skype on.

3. Close Other Apps Using the Camera

Only one application can typically use a webcam at a time. Make sure Zoom, Teams, or other video apps are fully closed before starting a Skype call.

4. Reinstall or Update Camera Drivers

For external webcams, unplug and reconnect the device. For built-in cameras, go to Device Manager → Cameras, right-click your camera, and select Update driver or Uninstall device (then restart to reinstall automatically).

When All Else Fails: Reinstall Skype

If none of the above steps resolve your issue, a clean reinstall often does the trick. Uninstall Skype, delete any leftover data in your app data folder, restart your computer, and install a fresh copy from the official Skype website.
