It’s hard to manage all of your applications on one screen. Adding another screen will ease the burden of flipping from window to window. It’s even better to handle your Skype contacts and calls on a different screen. But your second monitor will be no help if the sound is not working. Here’s why and what to do.

Skype was once the most popular Voice Over IP (VoIP) communication application. Acquired by Microsoft in 2011, this application works excellently at connecting loved ones over the internet. Skype allows you to communicate using video and voice in real-time.

Understandably, those working or studying from home can find value in dual monitors. Using an external monitor with your laptop can give you more room to manage your Skype communications.

However, it is frustrating when you are having trouble with the sound on your external monitor. Let’s dive into why your Skype sound might not be working on a second monitor.

Most importantly, check the monitor and computer to rule out a hardware issue. Start by:

  2. Check the original computer or laptop’s sound.
    1. Go into your system’s settings and click sounds on the original device. Ensure that the output device is your second monitor.
    1. Then check the volume and mute settings.
  3. Confirm speakers and headphones are working
    1. Use another device to establish sound on the speakers or headphones.
  4. Verify the cable connection.
    1. The HDMI cable connection should be secure. If you have another HDMI cord, try to use that one.
    1. If you are using a VGA cable, you must connect the cable from the AUDIO/LINE/HEADPHONE OUT port on the original device to the AUDIO/LINE IN on your second monitor. Try another VGA cable if you have one on hand.
  5. Establish sound on the second monitor.
    1. Verify that sound is working on your second monitor by creating sound. Try to play music.
  6. Update audio drivers
    1. In the taskbar search box, type Device Manager > click Device Manager > select a category to see your devices > right click on the device you’d like to update.
    1. Search for updated driver software > select Update Driver
