# What If Screen Sharing Has No Computer Audio?

> Fix the common issue of no system audio during screen sharing on Mac and Windows—covers permission grants, audio device selection, and driver installation.

## The “Share Computer Audio” Option Was Not Selected

When you share your screen in a video meeting, if **Share Computer Audio** is not selected in the sharing window, DingTalk does not transmit the sound from videos or audio clips on your computer. Remote participants may see the screen but hear no sound.

## Solution

1. In the video meeting, after clicking **Share**, first confirm that **Share Computer Audio** is selected in the lower-left corner of the pop-up, then choose the screen or window you want to share.

2. If you are already sharing your screen, click the arrow icon next to **New Share** in the top control bar, then select **Share Computer Audio** in the sharing options.
