We have prepared a few methods which might help you resolve the problem and we hope you check them out before calling it quits. Follow the steps below carefully and good luck!

What Causes Skype “Share System Sound” Not to Work on Windows?

There aren’t many causes which prevent the “Share system sound” feature to function improperly in Skype but it’s possible to find two distinct scenarios which account for at least 90% of the problem’s occurrences. Check it out below in order to prepare for troubleshooting the problem!

  • Windows is interfering – Windows sometimes decides to disable system sounds when it detects that a call is incoming or outgoing. That makes sense for regular calls but the “Share system sound” requires the opposite. This can be resolved in Windows or in the Skype client.
  • Old or faulty audio drivers – Audio drivers pretty much control everything related to sound on your computer and if they are faulty, many errors are bound to appear, including this one. Make sure you update them as soon as possible!

Solution 1: Do Nothing When Windows Detects Communications Activity

This option inside Sound settings in Control Panel is used to silence your computer if it notices any communications activity such as incoming or outgoing calls. However, this comes into conflict with the Skype “Share system sound” option as you definitely don’t want to silence sound on your computer. Performing the steps below should clear this confusion!

  1. Right-click on the volume icon located at your taskbar and choose the Sounds If this icon is not located at your taskbar, you can locate Sound settings by opening Control Panel, switching the view to Category and selecting Hardware and Sound >> Sound.

Solution 2: Stop Automatically Adjusting Speaker Settings

This method is largely similar to Solution 1 because of the fact it deals with automatic audio adjustment when a call is being made or received. This time, however, the option to change audio settings is located in the Skype client. Skype can also manage the audio levels which change when a call is made and you should disable that by following the steps presented below!

  1. Open Skype by double-clicking its icon from Desktop or by searching for it after opening the Start menu and left-clicking the top result.

File Explorer will show the hidden files and will remember this option until you change it again.
