If your sound is coming from the wrong device—like your monitor instead of your headphones—this guide will help you fix it in Windows 10.
Step 1: Quickly Switch Audio Devices from Taskbar
-
Click the speaker icon in the bottom-right corner of your screen (system tray).
-
Click the arrow (˄) next to the volume slider.
-
Select the correct device (e.g., “Speakers,” “Headphones,” or “Realtek Audio”).
This immediately changes where your sound plays.
Step 2: Set the Default Playback Device via Sound Settings
-
Right-click the speaker icon in the system tray.
-
Click Open Sound settings.
-
Under Output, use the dropdown to select the correct playback device.
-
If it doesn’t show up, ensure the device is plugged in and powered on.
Step 3: Update or Reinstall Audio Drivers
-
Press Windows + X → choose Device Manager.
-
Expand Sound, video and game controllers.
-
Right-click your audio driver (e.g., Realtek or High Definition Audio) → select Update driver → Search automatically.
-
Restart your computer afterward.
Step 4: Use App-Specific Sound Settings (Optional)
If only one app plays sound to the wrong device:
-
Go to Settings → System → Sound.
-
Scroll down and click App volume and device preferences under Advanced sound options.
-
Assign a specific output device to individual apps (e.g., route Spotify to headphones).
Tips for Troubleshooting
-
Unplug/replug headphones or speakers to reinitialize them.
-
Make sure Bluetooth audio devices are paired and connected.
-
Restart apps that were open while switching devices (they may not switch automatically).
