Adjust Volume Settings: Access Sound Settings, adjust volume levels, and ensure correct output device selection
To make sound play on your second display in Windows 10, start by checking your volume settings. Incorrect volume levels or an improperly selected output device can silently sabotage your efforts. Open the Sound Settings by right-clicking the volume icon in the system tray and selecting *Open Sound settings*. Here, you’ll find a list of output devices. Ensure the correct device (e.g., your second monitor’s built-in speakers or connected external speakers) is selected as the default. If the device isn’t listed, it may not be recognized by Windows, requiring a driver update or reconnection.
Once the correct output device is selected, adjust the volume levels to ensure sound is audible. In the same Sound Settings menu, click on the device and select *Device properties*. Here, you can fine-tune the volume using the slider or test the speakers to confirm functionality. Be mindful of balance settings, as uneven distribution can make audio seem absent or distorted on one display. If using multiple audio devices, consider muting unused outputs to avoid interference.
A common oversight is the exclusive mode setting, which can block applications from sharing audio devices. Disable this by navigating to the *Additional device properties* within the device settings and unchecking *Allow applications to take exclusive control of this device*. This ensures all applications can route audio to the selected device without conflicts. If sound still doesn’t play, restart the application or reboot the system to refresh audio drivers.
For dual-display setups, verify that the application sending audio is configured to use the correct output device. Some media players or communication tools have their own audio settings, overriding system defaults. Check these in-app settings to ensure they align with your system configuration. If troubleshooting persists, use the Windows Troubleshooter for audio devices, accessible via the *Update & Security* settings under *Troubleshoot*.
Finally, consider the physical connections of your second display. If it has built-in speakers, ensure the audio cable (e.g., HDMI or DisplayPort) is securely connected to both the monitor and your PC. External speakers connected to the second display should be powered on and set to the correct input. While software settings are critical, overlooking hardware connections is a frequent culprit in audio playback issues. By systematically addressing volume levels, device selection, and physical setup, you can reliably enable sound on your second display in Windows 10.

Check Mute Status: Verify mute buttons on keyboard, taskbar, and app settings are disabled
Before diving into complex troubleshooting, start with the simplest solution: check if your system is muted. Mute functions can be activated in multiple places—your keyboard, taskbar, or even within the application itself. A single overlooked mute button can render your display 2 silent, regardless of your configuration efforts.
Step-by-Step Verification:
- Keyboard Mute Button: Look for a dedicated mute key, often marked with a speaker icon and a strike-through line. Press it to toggle mute on or off. Some keyboards require holding the "Fn" key while pressing the mute button.
- Taskbar Volume Control: Click the speaker icon in the Windows taskbar. Ensure the volume slider is above zero and the mute button (speaker icon with a red slash) is inactive.
- App-Specific Settings: Open the application running on display 2 (e.g., media player, video conferencing tool). Check its internal audio settings for mute options or volume adjustments.
Cautions:
- Some keyboards have multiple audio controls (e.g., master volume, app-specific mute). Test all relevant keys.
- Third-party audio software (e.g., Equalizer APO, Voicemeeter) may override system settings. Temporarily disable them to isolate the issue.
Takeaway: Mute functions are often the culprit behind silent displays. Systematically checking each potential mute source ensures you don’t waste time on advanced fixes when a simple toggle is the solution. This step is quick, requires no technical expertise, and should always be your first troubleshooting action.

Enable Display Audio: Ensure HDMI or DisplayPort audio is enabled in Sound Settings
To make sound play through your second display on Windows 10, one critical step often overlooked is ensuring HDMI or DisplayPort audio is enabled in your Sound Settings. These ports aren’t just for video—they can carry audio signals too, but Windows doesn’t always default to using them. If your second display has built-in speakers or you’re connecting to an external audio device via the monitor, this setting is essential. Start by right-clicking the volume icon in your taskbar and selecting *Sounds* or *Open Sound Settings*. From there, navigate to *Device Manager* or directly to *Sound Control Panel* to verify if the HDMI or DisplayPort device is listed as an audio output option. If it’s missing, your drivers may need updating or the port isn’t configured correctly.
Analyzing why this step is crucial reveals a common oversight in multi-display setups. Windows 10 prioritizes audio devices based on their order in the playback list, often defaulting to internal speakers or headphones. HDMI and DisplayPort audio outputs are treated as separate devices, and if they’re disabled or not set as the default, sound won’t route through them. This is particularly frustrating when users assume their monitor’s speakers should work automatically. By enabling and setting the HDMI/DisplayPort audio as the default device, you ensure seamless audio redirection without relying on manual switching every time you connect the second display.
Here’s a step-by-step guide to enable HDMI or DisplayPort audio: First, open *Settings > System > Sound*. Under *Output*, check if your HDMI or DisplayPort device appears in the list. If it’s missing, right-click the volume icon, select *Sounds*, and go to the *Playback* tab. If the device still isn’t listed, update your graphics driver—outdated drivers often fail to recognize audio capabilities. Once visible, right-click the device, select *Enable*, and then set it as the default by clicking *Set Default*. Test the audio by playing a video or system sound to confirm it’s working. If issues persist, restart your PC or check for Windows updates, as some fixes require system reboots to take effect.
A practical tip to avoid future headaches: after enabling HDMI/DisplayPort audio, adjust the volume levels independently for each device. Some monitors have low default volumes, and balancing the output ensures consistent sound across displays. Additionally, if you frequently switch between audio devices, consider using third-party tools like SoundSwitch or Volume2 for quicker toggling. These tools provide shortcuts and automation, saving time compared to navigating Windows settings repeatedly.
In conclusion, enabling HDMI or DisplayPort audio in Sound Settings is a straightforward yet often missed step in configuring dual-display audio on Windows 10. By understanding how Windows prioritizes audio devices and following the steps outlined, users can avoid common pitfalls and enjoy uninterrupted sound from their second display. This small adjustment transforms a potentially frustrating experience into a seamless setup, proving that sometimes the solution lies in the details.
