Windows 10 offers a wealth of customization options, and one often overlooked feature is the ability to play audio through multiple devices simultaneously. This can be incredibly useful in a variety of situations, from hosting a party where you want sound throughout your home to creating a personalized listening experience tailored to your specific needs. Whether you want to use headphones and speakers at the same time, or send audio to different rooms, Windows 10 provides several methods to achieve this. This guide provides a detailed walkthrough of different methods for playing audio through two devices in Windows 10.
Understanding Audio Output Options in Windows 10
Before diving into the specifics, it’s important to understand how Windows 10 manages audio output. Your computer likely has multiple audio output devices, including built-in speakers, headphones connected via a 3.5mm jack, USB headphones, Bluetooth speakers, and even HDMI connections to TVs or monitors. Windows 10 identifies each of these as distinct audio output devices and allows you to choose which one to use as the primary output. However, by default, only one device can be selected as the primary output.
Windows handles sound output primarily through drivers installed for each audio device. These drivers translate the digital audio signals into a format that the hardware can understand and reproduce. Different drivers might offer different features or levels of customization, but their basic function remains the same: to control how audio is delivered to your speakers or headphones.
It’s also crucial to ensure that your audio drivers are up to date. Outdated or corrupted drivers can cause various audio issues, including the inability to play audio through multiple devices. Regularly checking for driver updates through Windows Update or the device manufacturer’s website can help prevent these problems.
Method 1: Using Stereo Mix to Enable Simultaneous Playback
Stereo Mix is a recording input that captures all audio being played through your computer. By enabling Stereo Mix and setting it as a listening device to a second output, you can effectively route audio to two devices at the same time. This is a common and often reliable method, but it may not be available on all systems, depending on your sound card and driver configuration.
Enabling Stereo Mix
First, you need to enable Stereo Mix if it’s currently disabled. To do this, right-click on the speaker icon in your system tray (usually located in the bottom-right corner of your screen) and select “Open Sound settings.”
In the Sound settings window, click on “Sound Control Panel” which is typically located on the right-hand side under related settings. This will open a new window.
In the Sound window, navigate to the “Recording” tab. Look for “Stereo Mix” in the list of recording devices. If you don’t see it, right-click in the empty space within the “Recording” tab and select “Show Disabled Devices.” This should make Stereo Mix visible.
If Stereo Mix is now visible but disabled, right-click on it and select “Enable.” Enabling Stereo Mix is the first crucial step.
Configuring Stereo Mix for Playback
Now that Stereo Mix is enabled, you need to configure it to output audio to your desired second device. Right-click on Stereo Mix again and select “Properties.”
In the Stereo Mix Properties window, go to the “Listen” tab. Check the box that says “Listen to this device.”
From the “Playback through this device” dropdown menu, select the second audio output device you want to use (e.g., your headphones if your primary output is speakers, or vice versa). This will route the audio captured by Stereo Mix to the selected device. Selecting the correct playback device is critical for this method to work.
Click “Apply” and then “OK” to save the changes. Now, audio should be playing through both your primary output device and the device you selected in the Stereo Mix properties.
Troubleshooting Stereo Mix
If you’re not hearing audio through both devices, double-check that Stereo Mix is enabled and configured correctly. Ensure that the correct playback device is selected in the “Listen” tab. Also, make sure that the volume level for Stereo Mix is not muted or set too low. Sometimes, restarting your computer after enabling Stereo Mix can resolve any lingering issues. Ensure volume levels are adequate on both devices and in the system settings.
Another potential issue is driver compatibility. If you’re still having problems, try updating your audio drivers to the latest version. You can usually find the latest drivers on the website of your sound card manufacturer (e.g., Realtek, Creative, etc.).
Method 2: Using Third-Party Audio Management Software
Several third-party audio management software programs offer advanced features for routing audio to multiple devices, often with more control and flexibility than the built-in Windows tools. These programs can be particularly useful if you need more granular control over audio routing or if the Stereo Mix method doesn’t work for you.
VoiceMeeter Banana
VoiceMeeter Banana is a popular and powerful virtual audio mixer that allows you to manage audio inputs and outputs with precision. It acts as a virtual sound card, allowing you to route audio from different sources to different outputs, including multiple devices simultaneously.
To use VoiceMeeter Banana, you’ll need to download and install it from the official website. Once installed, launch the program.
In VoiceMeeter Banana, you’ll see several virtual inputs and outputs. The “Hardware Input 1” and “Hardware Input 2” can be assigned to your physical input devices (e.g., microphone). The “Virtual Input” section is where your system audio will be routed. The “Hardware Out A1” and “Hardware Out A2” are your physical output devices.
To route audio to two devices, select your primary output device (e.g., speakers) in the “Hardware Out A1” dropdown menu. Then, select your second output device (e.g., headphones) in the “Hardware Out A2” dropdown menu.
Next, in the “Virtual Input” section (labeled “VoiceMeeter Input”), click both the “A1” and “A2” buttons. This will route the system audio to both output devices you selected.
Finally, you need to set VoiceMeeter Input as your default playback device in Windows. Go to Sound settings (right-click on the speaker icon in the system tray and select “Open Sound settings”).
In the Sound settings window, under “Output,” select “VoiceMeeter Input” as your default output device.
Now, all audio from your computer will be routed through VoiceMeeter Banana and output to both devices you selected in the program. Configuring VoiceMeeter Banana correctly is crucial for achieving the desired audio routing.

Besides VoiceMeeter Banana, other audio management software options are available, such as Equalizer APO with Peace GUI and Virtual Audio Cable. These programs offer similar functionality but may have different interfaces and features. Exploring these alternatives can help you find the software that best suits your needs.
Method 3: Utilizing Multiple Sound Cards or USB Audio Adapters
If you have multiple sound cards installed in your computer or use USB audio adapters, Windows 10 can treat each one as a separate audio output device. This provides a straightforward way to play audio through two devices without relying on Stereo Mix or third-party software.
Connecting and Configuring Multiple Devices
First, ensure that both sound cards or USB audio adapters are properly connected to your computer and that the necessary drivers are installed. Windows 10 should automatically detect and install the drivers for most common audio devices.
Once both devices are connected and recognized, go to Sound settings (right-click on the speaker icon in the system tray and select “Open Sound settings”).
In the Sound settings window, you should see both audio devices listed under “Output.” You can select each device to configure its specific settings, such as volume level and default format.
Using Applications with Output Device Selection
To play audio through both devices simultaneously, you’ll need to use applications that allow you to select the output device manually. Many media players, such as VLC Media Player and foobar2000, offer this feature.
In VLC Media Player, for example, you can go to “Tools” > “Preferences” > “Audio” and select the desired output device from the “Output module” dropdown menu. You can run two instances of VLC Media Player, each configured to output audio to a different device. This way, you can play the same audio file through both devices simultaneously. This is particularly useful for sending different streams to different zones.
Similarly, foobar2000 allows you to configure multiple output devices through its settings. By using plugins like “Multiple Output,” you can route audio to several devices simultaneously.
Limitations of Multiple Sound Cards
While using multiple sound cards or USB audio adapters is a relatively simple method, it has some limitations. You’ll need to use applications that allow you to select the output device manually, and you may need to run multiple instances of the same application to play audio through both devices simultaneously. Also, managing volume levels for each device separately can be a bit cumbersome.

Remember to keep your drivers updated and explore the different methods to find the one that best suits your needs.
Can I play different audio on each device, or only the same audio mirrored?
Windows 10 primarily allows you to mirror audio across multiple output devices using the methods described in the guide. This means you’ll typically be listening to the same sound on both your headphones and speakers simultaneously. While this is perfect for scenarios like sharing music or ensuring audio coverage in a larger space, playing completely different audio streams natively isn’t a built-in function of Windows 10’s sound settings.
However, there are workarounds and third-party software solutions that can achieve this. These solutions often involve creating virtual audio devices or utilizing applications designed for audio routing. These tools allow you to direct specific applications’ audio to specific output devices, effectively enabling you to play different sounds on your headphones and speakers simultaneously. You’d need to research and install appropriate software to accomplish this functionality.
Will I experience audio delay or latency when using multiple output devices?
Yes, it’s possible to experience audio delay or latency when using multiple audio output devices. The mirroring process requires Windows to synchronize the audio streams across different hardware, which can introduce a slight delay. This delay might be more noticeable on some systems than others, depending on factors like the processing power of your computer, the audio drivers being used, and the quality of the audio devices themselves.
To minimize latency, ensure your audio drivers are up-to-date and that your computer meets the system requirements of the audio software you’re using. You can also experiment with different buffering settings within your audio software, if available. In some cases, using higher-quality audio interfaces or sound cards can also help reduce latency by providing more efficient audio processing.
What happens if one of my audio devices is Bluetooth?
Using a Bluetooth audio device alongside a wired one can introduce additional challenges. Bluetooth connections inherently have some latency due to the wireless transmission process and the need for encoding and decoding the audio signal. This latency can be more pronounced compared to wired connections, potentially leading to noticeable synchronization issues when mirroring audio.
When using Bluetooth, ensure that you have the latest drivers for your Bluetooth adapter and audio device. Experiment with different Bluetooth codecs if your devices support them; some codecs may offer lower latency than others. If latency is a significant issue, consider using a wired connection for both audio devices to ensure the best possible synchronization.
How do I revert back to a single audio output device?
Reverting to a single audio output device is straightforward. If you were using the “Listen to this device” method, simply go back to the Sound settings, select the Recording tab, choose your microphone, click Properties, go to the Listen tab, and uncheck the “Listen to this device” box. This will stop the audio from being routed to the secondary output device.
If you were using the Stereo Mix or similar method, go to the Sound settings, Playback tab, and disable the Stereo Mix device (or whatever device you enabled for mirroring). Then, set your preferred single audio output device (e.g., your headphones or speakers) as the default device. This will direct all audio to that single output, effectively disabling the mirroring setup.
Is it possible to control the volume of each audio device independently?
Controlling the volume of each mirrored audio device independently can be tricky but is often possible. The basic Windows volume mixer usually only controls the overall system volume, affecting both devices simultaneously. However, some audio drivers or third-party applications provide more granular control.
Look for a volume control utility specific to your sound card manufacturer. These utilities sometimes offer individual volume sliders for each output device. Alternatively, some third-party audio management software allows you to route audio from specific applications to specific output devices and control their volume independently. Explore these options to gain more precise volume control over your mirrored audio setup.
What should I do if I experience crackling or distorted audio?
Crackling or distorted audio when using multiple output devices can be caused by several factors. It could be due to driver issues, resource limitations on your computer, or conflicts between audio devices. Start by ensuring that all your audio drivers are up to date. Visit the websites of your sound card manufacturer and the manufacturers of your audio devices to download the latest drivers.
If updating drivers doesn’t resolve the issue, try increasing the buffer size in your audio settings (if available). A larger buffer can give your computer more time to process the audio and prevent dropouts. Also, close any unnecessary applications that might be consuming system resources. If the problem persists, consider testing with different audio cables or a different audio interface to rule out hardware issues.
Will using multiple audio output devices impact my computer’s performance?
Yes, using multiple audio output devices can have a slight impact on your computer’s performance. Mirroring audio requires the operating system to process and synchronize audio streams across multiple devices, which consumes CPU and memory resources. The extent of the impact depends on your computer’s specifications, the quality of the audio, and the number of output devices being used.
For modern computers with sufficient processing power, the performance impact is usually minimal and not noticeable during everyday tasks. However, on older or less powerful systems, you might experience a slight slowdown or a decrease in performance, especially when running resource-intensive applications like games or video editing software. If you notice performance issues, consider closing unnecessary applications or upgrading your computer’s hardware.
