Voicemeeter is a popular virtual audio mixer for Windows that allows users to manage multiple audio sources easily. However, sometimes users face issues with the Voicemeeter output device not working correctly on Windows 11. This can disrupt audio playback and recording.

Fixing this problem usually involves checking audio settings, device configurations, and software updates. Many solutions are straightforward and can be done without advanced technical knowledge.

In this article, you will find step-by-step instructions to resolve Voicemeeter output device problems on Windows 11. Each step is explained clearly to help you troubleshoot effectively.

By following these solutions, you should be able to restore proper audio functionality with Voicemeeter quickly.

Quick Note: Prerequisites and Basic Checks

Ensure Voicemeeter is installed correctly: Make sure you have the latest version of Voicemeeter downloaded from the official website.
Check Windows 11 audio updates: Keep your operating system up to date to avoid compatibility issues.
Verify your audio hardware: Confirm that your speakers, headphones, or sound cards are working properly outside of Voicemeeter.
Restart your computer: Sometimes a simple reboot fixes temporary glitches.

Step 1: Set Voicemeeter as the Default Playback Device

One common cause of the Voicemeeter output device not working is that it is not set as the default playback device. Windows needs to know where to send the audio output.

Right-click the speaker icon on the Windows taskbar (bottom-right corner).
Select Sound settings from the menu.
In the Sound settings window, click on Choose where to play sound.
Locate Voicemeeter Input or Voicemeeter VAIO in the list.
Click on it and then click the Set Default button.

By setting Voicemeeter as the default device, you direct Windows audio through it, ensuring Voicemeeter can process the sound correctly.

Step 2: Check Voicemeeter Hardware Out Settings

Voicemeeter needs to be connected properly to your physical audio devices to output sound. This is done through the “Hardware Out” section in the Voicemeeter interface.

Open the Voicemeeter application.
Look at the top-right corner labeled A1, A2, and A3 (these represent hardware outputs).
Click on A1 to select your physical audio output device (e.g., your headphones or speakers).
Choose the correct device from the dropdown list. It usually shows your sound card or USB headphones.
If you use multiple devices, set A2 or A3 similarly.

Without setting a proper hardware output, Voicemeeter will not be able to send audio to your actual speakers or headphones.

Step 3: Restart Voicemeeter and Windows Audio Services

Sometimes, Voicemeeter or the Windows audio services may freeze or malfunction. Restarting them can fix these temporary issues.

Close the Voicemeeter application completely.
Press Windows + R to open the Run dialog box.
Type services.msc and press Enter to open the Services window.
Scroll down and find Windows Audio.
Right-click it and choose Restart.
Optionally, find Windows Audio Endpoint Builder and restart it as well.
After restarting these services, reopen Voicemeeter and check if the output works.

Restarting audio services refreshes the communication between Windows and audio devices, resolving many sound-related problems.

Step 4: Check Windows Sound Control Panel Settings

Voicemeeter interacts with Windows sound devices, so it’s important to configure audio properties correctly.

Right-click the speaker icon in the taskbar and select Sounds.
Go to the Playback tab.
Find Voicemeeter Input or Voicemeeter VAIO in the list.
Right-click it and select Properties.
Navigate to the Advanced tab.
Ensure the default format is set to a standard value like 24 bit, 48000 Hz (Studio Quality).
Uncheck the option Allow applications to take exclusive control of this device to prevent conflicts.
Click Apply and OK.

These settings help avoid conflicts between applications trying to control audio devices, supporting smoother Voicemeeter operation.

Step 5: Update or Reinstall Audio Drivers

Outdated or corrupted audio drivers can cause Voicemeeter output issues. Updating or reinstalling drivers can fix this.

Press Windows + X and select Device Manager.
Expand the Sound, video and game controllers section.
Right-click your audio device (like Realtek, Intel, or USB audio) and select Update driver.
Choose Search automatically for updated driver software and follow the prompts.
If updating doesn’t help, right-click the device again and select Uninstall device.
Restart your computer to let Windows reinstall the drivers automatically.

Fresh drivers ensure compatibility between Windows 11, your hardware, and Voicemeeter.

Alternative Method: Use Voicemeeter Banana or Potato

If you are using the basic Voicemeeter version and still face issues, consider upgrading to Voicemeeter Banana or Voicemeeter Potato. These versions offer more advanced controls and better device management, which can improve output handling.

Download the upgraded versions from the official Voicemeeter website and follow the installation instructions. The interface is similar but with added features that may resolve complex audio routing problems.
