If you follow the steps outlined but you still can’t screen share your system’s audio, here are a few troubleshooting methods: Method 1: Verify That Your Current Audio Device Is the Default Audio Device Under Settings To do so: 1. Open Skype and click on “Audio and Video” and check whether the device currently in use is selected. 2. Adjust the volume if the level is too low. Method 2: Adjust Your Computer’s Audio Settings When your computer detects active communication such as an outgoing call, sometimes it will automatically mute all system sounds in an attempt to ensure that your call is as smooth as possible. However, doing so puts it in direct conflict with Skype’s system sound sharing feature. Here’s how you can undo your computer’s actions: 1. Open the control panel section and click on “Hardware and Sound.” 2. Click on “Sound.” 3. Click on “Communications.” 4. Check the box next to “Do Nothing.” Method 3: Update Your Audio Driver If none of the above troubleshooting options work, your audio driver could be the culprit. Updating the driver could solve the problem. Here’s how to do it: 1. Open the “Device Manager” section and click on “Sound, Video, and Game Controllers.” 2. Click on your audio driver and select “Update.”
