How to fix Sound issues when you share your Computer’s Sound in Microsoft Teams

Sharing your computer sound in Microsoft Teams lets meeting participants hear video and audio clips directly from your system by broadcasting your PC audio alongside your visuals. When shared audio fails to come through or sounds too quiet, incorrect audio device settings or disabled background sharing options usually cause the problem.

Fixing these audio problems takes just a few clicks in your Windows sound settings and the Teams meeting toolbar. You can turn on the system audio toggle and pick the right playback device to make sure everyone on your call hears your videos loud and clear.

Fixing Low Shared Sound

Windows automatically lowers background sound levels when it detects an active communication session, which often makes shared audio too quiet for remote attendees.

What are Windows Communication Settings?

Operating system audio settings reduce other sound volumes during calls to improve focus on conversations. However, this attenuation feature ruins the playback volume of shared multimedia.

Adjusting Sound Settings for Clearer Audio

Disabling this automatic volume ducking (the process of lowering audio levels when communication is detected) keeps shared computer audio clear and audible for everyone in the meeting. Right-click the speaker icon in your taskbar 🖥️ to open the audio menu.

1. Open the Sound Control Panel 🎛️

   The fastest way is to right-click the speaker icon in your Windows taskbar (usually in the bottom-right corner). In the menu that appears, choose "Sounds." This opens the Sound control panel.

   💡Tip

   If you don't see "Sounds" right away, you might need to click "Open Sound settings" first. Then, look for a link called "Sound Control Panel" on the right side of that window.

2. Go to the "Communications" Tab

   In the Sound control panel window, you'll see tabs at the top like Playback, Recording, Sounds, and Communications. Click on the Communications tab.

3. Select "Do Nothing"

   Under the Communications tab, you'll see options. Find the one that says something like "When Windows detects communications activity." Select the circle next to Do nothing. This tells Windows to keep all volumes just as you set them, even during a Teams meeting.

   ⚠️Warning

   Make sure you choose "Do nothing." The other options will keep lowering your volume.

4. Apply Your Changes

   After choosing "Do nothing," click the Apply button, then click OK to close the Sound control panel. Your changes are saved right away.

Summary

Operating system call-detection routines frequently suppress media playback levels during active conferences.
