Many people will agree that the operating system’s virtual assistant, Cortana, is quite handy for different computing tasks. However, it is still prone to certain issues. For instance, many users complained about the Cortana speaker not working.

What if Cortana Has no Voice?

A lot of users rely on Cortana to perform crucial tasks on a daily basis. However, some of them reported that they had been experiencing audio issues with the virtual assistant. Before we learn how to fix the no sound from Cortana problem in Windows 10, it is best that we discuss some scenarios related to the issue.

  • Cortana doesn’t speak – A lot of users complained about Cortana not speaking. Keep in mind that the feature will only talk to you when you send voice commands via the microphone.
  • Cortana has no voice – It is possible that you had Quiet hours enabled. If Cortana has no voice, you can try disabling Quiet hours.
  • Cortana doesn’t have sound – When your audio drivers are outdated or damaged, you might encounter audio issues with Cortana.
  • Cortana not functioning on Windows 10 – In some cases, third-party applications can interfere with Cortana. You can try removing these software programs from startup to resolve the issue.
  • Cortana speaker not working – Many users also complained about the Cortana speaker not working. You should be able to fix this issue using one of our methods below.
  • No sound is coming from Cortana – Make sure you remove hidden audio devices to ensure that Cortana will produce sound.

Method 1: Disabling Digital Output

One of the solutions you should try is going to your sound settings and disabling the digital output. When you enable two playback devices on your PC, one of them can interfere with Cortana. This is not supposed to happen, but in some cases, the secondary audio device tends to block Cortana. Follow the steps below to fix the issue:

  1. Go to your taskbar, then right-click the Sound icon which you can find at the lower-right corner.
  2. Select Playback Devices.
  3. Look for the Digital Output that you’re not using. Disable it.
  4. Restart your PC.

Most people who tried this workaround were able to fix their audio issues with Cortana. However, if the issue persists, you can try one of our solutions below.

Method 2: Resetting Cortana

You can also try bringing back Cortana to its default settings. Here are the steps:

  1. Launch Cortana, then go to Settings.
  2. You should be able to disable Cortana using the first button. You will see the following message:

“Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud.”

  1. Restart your computer, then enable Cortana.

Keep in mind that this method will prompt Cortana to forget all your settings completely. So, it will think that you’ve just installed Windows. Also, if Cortana is not supported in your region, you might have to change your regional and language settings.

Method 3: Disabling Quite Hours

Windows 10 allows users to block notifications, using a feature called Quiet hours. If you enabled this feature, Cortana might not be able to produce sound. To disable Quiet hours, simply follow the instructions below:
