Windows 10 provides several ways to output audio to two different devices simultaneously, allowing for flexible audio setups whether you want to share sound, stream, or monitor audio. The most common method involves using the built-in Stereo Mix feature, while third-party software offers more advanced control.
Method 1: Utilizing Stereo Mix (Built-in Feature)
The "Stereo Mix" feature, often referred to as "What U Hear," allows you to route your primary audio output to a secondary device. This effectively duplicates the sound playing through your default speakers or headphones to another set of audio outputs.
Step-by-Step Guide for Enabling Stereo Mix:
To set up Stereo Mix, follow these clear instructions:
-
Access Sound Settings:
- Right-click the speaker icon located in the system tray (typically in the bottom-right corner of your screen).
- Select "Sounds" from the context menu. This will open the Sound dialog box.
-
Enable Stereo Mix:
- In the Sound dialog box, navigate to the "Recording" tab.
- Look for "Stereo Mix" in the list of recording devices.
- If Stereo Mix is not visible: Right-click anywhere in the empty space within the "Recording" tab and ensure that "Show Disabled Devices" and "Show Disconnected Devices" are both checked. Stereo Mix should then appear.
- Once visible, right-click "Stereo Mix" and select "Enable."
-
Configure Stereo Mix Properties:
- Right-click "Stereo Mix" again and choose "Properties."
- Go to the "Listen" tab within the Stereo Mix Properties window.
-
Select Secondary Output Device:
- Tick the box next to "Listen to this device."
- From the "Playback through this device" drop-down menu, select the secondary audio device where you want the sound to play (e.g., your headphones, a different set of speakers, or another connected audio interface).
-
Apply Settings:
- Click "Apply" and then "OK" on both the Stereo Mix Properties window and the main Sound dialog box to save your changes.
-
Verify Primary Output (Optional):
- Go to the "Playback" tab in the main Sound dialog. Ensure your primary audio device (the one you want to hear most of the sound from, or the main source) is set as the default playback device.
Once configured, any audio playing through your default playback device will also be routed to the secondary device you selected in the Stereo Mix "Listen" settings.
Method 2: Leveraging Third-Party Audio Software
For more advanced control, greater flexibility, or if Stereo Mix is unavailable or doesn't meet your needs, various third-party applications can manage multiple audio outputs. These tools often allow for per-application audio routing, advanced mixing, and virtual audio devices.
Popular Third-Party Solutions:
- Voicemeeter Banana/Potato: These free (donationware) virtual audio mixers by VB-Audio provide extensive control over audio inputs and outputs. They allow you to route audio from different applications to multiple physical output devices, mix various input sources, and apply effects. While powerful, they have a steeper learning curve due to their comprehensive features.

- CheVolume (or similar software): Applications like CheVolume focus on per-application audio routing. This means you can direct sound from a web browser to one output (e.g., speakers) while your game audio goes to another (e.g., headphones).
- Equalizer APO with Peace GUI: While primarily known as a system-wide equalizer, Equalizer APO, when combined with its graphical interface (Peace GUI), offers advanced possibilities for audio routing and manipulation that can be configured for multi-output scenarios.

These advanced tools often provide capabilities beyond simple duplication, such as sending specific applications to different outputs, which isn't possible with Stereo Mix alone.
Method 3: Using Multiple USB Audio Devices or Sound Cards
If you have multiple distinct audio hardware components—such as an integrated motherboard audio chip, a dedicated sound card, and several USB audio devices (e.g., a USB headset, USB speakers, or a USB audio interface)—Windows can often manage them independently.
Here's how this can be utilized:
- Direct Application Output: Many modern applications, especially media players, communication software (like Discord, Zoom), and some games, allow you to specify their audio output device directly within their internal settings. You could, for instance, set your music player to output to your default speakers and your communication app to your USB headset.
- Virtual Audio Cable Software: Some third-party software creates virtual audio cables that can act as additional "devices" in your sound settings. You can then route audio through these virtual cables and direct them to different physical outputs.
This method relies on both your applications and Windows' ability to differentiate and route audio to separate hardware components, offering a more flexible setup for specific use cases.
Important Considerations for Dual Audio Output
When setting up dual audio outputs, keep the following in mind for the best experience:
- Audio Quality and Latency: Routing audio through multiple layers, especially with virtual cables or complex software, can sometimes introduce slight latency (delay) or, in rare cases, minor degradation in audio quality.
- Driver Compatibility: Always ensure that the drivers for all your audio devices are up-to-date. Outdated drivers can lead to compatibility issues or poor performance. You can typically check for updates via Windows Update or directly from your device manufacturer's website.
- System Resources: While typically light, running complex audio routing software might consume a small amount of system resources, which could be a factor on older or less powerful PCs.
- Application-Specific Settings: Always check the audio output settings within individual applications. Some apps might override global Windows settings or offer their own dedicated output options, which can be useful for granular control.
Troubleshooting Common Issues
| Issue | Potential Cause | Solution |
|---|---|---|
| Stereo Mix not visible | Disabled or hidden device | In the "Recording" tab of Sound settings, right-click an empty space and ensure "Show Disabled Devices" and "Show Disconnected Devices" are checked, then enable Stereo Mix. |
| No sound from secondary device | Incorrect default playback device or routing error | Ensure your primary device is set as default in the "Playback" tab. Double-check Stereo Mix's "Listen" settings and confirm the correct secondary device is selected. If using third-party software, verify its routing matrix. Test each audio device individually. |
| Audio quality issues | Driver problems, latency, resource contention | Update audio drivers from the manufacturer's website. Reduce buffer sizes if using third-party software (if applicable). Close unnecessary background applications to free up resources. Ensure sample rates match across devices/software if possible. |
| Echoing/Feedback | Stereo Mix outputting back to input | Ensure "Listen to this device" in Stereo Mix is correctly set to output to a different playback device, not accidentally routing back to a recording input. Adjust microphone monitoring settings if applicable. |
Benefits of Dual Audio Output
Enabling dual audio output on your Windows 10 PC offers several practical advantages:
- Shared Listening: Enjoy watching a movie or listening to music with headphones while simultaneously allowing others to hear it through speakers.
- Gaming & Streaming: Privately listen to your game audio through headphones for competitive play, while simultaneously sending the game sound to your live stream audience or local speakers.
- Audio Monitoring: For content creators, producers, or DJs, dual output allows for monitoring audio on studio reference speakers and a pair of headphones at the same time.
- Personalized Audio: One person can use headphones for a private video call or podcast, while another can listen to background music or system sounds through speakers without interference.
By understanding and utilizing these methods, you can effectively manage and route your audio outputs on Windows 10 to suit diverse listening needs, improving your multimedia and communication experience.
