Question:

How can I configure Windows 10 to output different audio sources to different monitors with built-in speakers?

I have a dual monitor setup, one connected via DP and the other via HDMI. Both monitors have speakers. I want to play a game on the main monitor and watch a video on the second monitor, and have the audio from each source come out of the corresponding monitor’s speakers. Is this possible, and if so, how can I achieve it?

Answer:

How to Output Different Audio Sources to Different Monitors in Windows 10

If you have a dual monitor setup with built-in speakers, you might want to play different audio sources on each monitor. For example, you might want to play a game on your main monitor and watch a video on your second monitor, and have the audio from each source come out of the corresponding monitor’s speakers. This can create a more immersive and enjoyable experience, as well as avoid audio interference.

However, Windows 10 does not have a native feature to assign different audio outputs to different applications. By default, it will use the same audio device for all applications, regardless of which monitor they are on. This means that you will hear both the game and the video sounds from the same speakers, which can be annoying and distracting.

Fortunately, there are some third-party solutions that can help you achieve this. In this article, we will show you how to use two of them: Audio Router and EarTrumpet. Both of these are free and easy to use, and they will allow you to output different audio sources to different monitors with built-in speakers.

Audio Router is a simple and lightweight tool that lets you route audio from different applications to different audio devices. You can download it from [here](https://github.com/audiorouterdev/audio-router/releases).

To use Audio Router, follow these steps:

1. Run Audio Router as administrator. You will see a list of all the applications that are currently producing sound, as well as the audio device that they are using.

2. Right-click on the application that you want to route to a different monitor, and select Route. A pop-up window will appear, showing you all the available audio devices.

3. Select the audio device that corresponds to the monitor that you want to use. For example, if you want to route the video sound to the second monitor, select the HDMI audio device. If you want to route the game sound to the main monitor, select the DP audio device.

4. Click OK. The application will now use the selected audio device, and you will hear the sound from the corresponding monitor’s speakers.

5. Repeat the same steps for any other applications that you want to route to different monitors.

Using EarTrumpet

EarTrumpet is another tool that lets you control the audio output of different applications. It also integrates with the Windows 10 taskbar, making it more convenient to use. You can download it from [here](https://www.microsoft.com/en-us/p/eartrumpet/9nblggh516xp).

To use EarTrumpet, follow these steps:

1. Run EarTrumpet. You will see a new icon in the taskbar, next to the default volume icon. Click on it to open the EarTrumpet menu.

2. You will see a list of all the applications that are currently producing sound, as well as the audio device that they are using. You can also see the volume level of each application, and adjust it as you wish.

3. To change the audio device of an application, click on the arrow next to its name. A drop-down menu will appear, showing you all the available audio devices.

4. Select the audio device that corresponds to the monitor that you want to use. For example, if you want to output the video sound to the second monitor, select the HDMI audio device. If you want to output the game sound to the main monitor, select the DP audio device.

5. The application will now use the selected audio device, and you will hear the sound from the corresponding monitor’s speakers.

6. Repeat the same steps for any other applications that you want to output to different monitors.
