Many people use their laptop cameras for video conferencing, virtual meetings, and streaming. While laptop cameras are useful for visual communication, they may not always be equipped with sound capabilities. In some cases, plugging in an external webcam may disable all audio inputs, causing the built-in laptop camera to stop working. This can be due to various factors, such as outdated drivers, privacy settings, or hardware issues. To ensure sound functionality with your laptop camera, it is important to check the audio settings, update drivers, and grant the necessary permissions for camera and microphone access.
| Characteristics | Values |
|---|---|
| Webcam disabling audio input | The issue could be due to the default audio input device being set to the microphone in the webcam. |

What You'll Learn
Privacy settings blocking access
Laptop cameras typically have sound, but issues with privacy settings can block access. If you're experiencing problems with your laptop camera's sound, it may be due to certain privacy settings on your device. Here are some steps to help you troubleshoot and resolve the issue:
Check Your Privacy Settings:
- Windows 11: Go to Start > Settings > Privacy & Security > Camera. Ensure that "Camera access," "Let apps access your camera," and the specific toggle for the app you want to use are all turned on.
- Windows 10: Go to Start > Settings > Privacy > Camera. Ensure "Camera access for this device" and "Allow apps to access your camera" are on. For a specific app, go to the Microsoft Store, find the app, and turn on camera access.
- For Desktop Apps: Desktop apps, such as Microsoft Edge and Microsoft Teams, require a separate setting. Go to "Let desktop apps access your camera" and ensure it's switched on.
- Check for Work Restrictions: If you use a work device or have a work account on your personal device, your organisation may control certain settings. Look for "Some settings are managed by your organisation" at the top of the Camera settings page.
- Windows Hello: If you use Windows Hello to sign in, it will access your camera even if the camera setting is off. To prevent this, turn off Windows Hello.
Review App Permissions:
- Windows 11: Go to Start > Settings > Privacy & Security > Microphone. Ensure "Microphone access," "Let apps access your microphone," and specific app toggles are on.
- Windows 10: Go to Start > Settings > Privacy > Microphone. Ensure "Microphone access for this device" and "Allow apps to access your microphone" are on. For specific apps, go to the Microsoft Store and enable access.
- Desktop Apps: Desktop apps may not appear in the list but can access the microphone even when settings are off. Go to "Allow desktop apps to access your microphone" and enable it.
Manage Site Permissions:
In Microsoft Edge, go to Settings > Cookies and Site Permissions > Camera or Microphone. Remove access for specific websites by selecting the trash can icon.
Additional Tips:
- If you use multiple speakers, ensure your chosen speaker is set as the default output device.
- If you use Bluetooth speakers, try switching the default output to internal speakers and then back to Bluetooth.

Outdated camera drivers
If your laptop camera is not producing sound, it could be due to outdated or incompatible drivers. To resolve this, you can update your camera drivers. Here's how:
- On your keyboard, press the Windows logo key and R at the same time to invoke the "Run" window.
- Type "devmgmt.msc" and press Enter to launch the Device Manager.
- In the Device Manager, expand the "Cameras" section and look for your camera from the list.
- Right-click on your camera and select "Update Driver".
- Choose "Search automatically for drivers". Windows will now search online for the latest driver and install it if available.
- Once the update is complete, restart your computer to ensure the changes take effect.
- After restarting, open the Camera app to test if the issue has been resolved.
If you cannot find your camera listed under the "Cameras" section, try looking under "Imaging devices" or "Sound, video and game controllers". If you still cannot find your camera, select the "Action" menu and then select "Scan for hardware changes".
Additionally, you can try manually updating your drivers by downloading the latest driver from the manufacturer's website and installing it yourself. This may be necessary if Windows cannot find a new driver or if you want to install a specific version of the driver.
If updating the drivers does not resolve the issue, there are a few other potential causes and solutions to explore. For example, ensuring that your privacy settings allow the application to access the camera and microphone or checking your audio input and output settings.

Incorrect default audio device
If your laptop camera does not have sound, it could be due to an incorrect default audio device setting. This issue is prevalent among Windows users, especially those who use Windows 10 and Windows 11.
When you plug in a webcam, your laptop might recognise it as an audio device first and a web camera secondary. This results in all other audio inputs being disabled, and the camera itself not working. This could be because the default audio input device is set to the microphone in your webcam, and the audio preferences for the camera are also set to default.
To fix this, you can try disabling the webcam microphone in the recording settings and choosing your laptop's internal microphone instead. You can do this by going to the Control Panel, clicking on Sound, and under the Recording tab, setting the default to your laptop's microphone. If you have multiple speakers, you will also need to set the one you are using as the default one.
Another solution could be to check if you have the correct drivers installed for your webcam. Generally, with a webcam, the system first installs a driver for a 'composite device', which then exposes interfaces for the audio and camera sections. If the imaging device is not showing up, you might need to install the proper drivers for it.
If you are using a Bluetooth speaker as your default audio device, switching the default audio output to your laptop's internal speakers and then back to the Bluetooth speakers might help resolve the issue.

Physical switch/button is off
If your laptop camera is not working, it could be because the physical switch or button that turns the camera on or off is off. Many laptops and portable devices have such a physical switch or button. When turned off, your device won't recognize that there's a camera installed, or it may cause your camera to show an image of a camera with a slash through it.
If your laptop has a physical switch or button, make sure it's in the on position before using your camera. These switches or buttons may not be easy to find, so make sure you check all possible places. For example, it could be a button on the keyboard that's activated with the Fn key, or a switch above the lens. HP laptops, for instance, have a camera key or a button on the side of the laptop, while Lenovo laptops usually use F8 or Fn+F8. Some laptops also have a privacy shutter or cover that can be slid over the camera to physically block it. Ensure this shutter is open.
If you are not sure, please hold down the Windows + R keys, type in msinfo32.exe and hit enter. Then share a screenshot of the System Information window.

Webcam disables audio input
Several factors can cause audio input to be disabled when plugging in a webcam. One common issue is that the audio from applications is being sent to the webcam, which is being treated as "Headphones". This can be resolved by going to the “Configuration” tab in Pulse Audio Volume Control and setting the audio profile to "Analog Stereo Duplex".
Another potential cause is that the webcam is disabling the built-in microphone on your device. In this case, you can try disabling the webcam in Device Manager by scrolling down to “Sound, video and game controllers" and disabling the device. This has been known to work for the Logitech C920 Webcam and similar models.
If you are using Windows, you may need to give specific apps permission to use the camera and microphone. To do this, go to Start > Settings > Privacy & Security > Camera and allow access to the camera on the device. You can also try rolling back the driver for your camera in Device Manager and restarting your device.
Additionally, it is important to rule out any hardware issues by testing the camera on a different device. Some laptops have a physical switch or button that turns the camera on or off, so ensure that it is in the "on" position.
If none of these solutions work, it may be a problem with the webcam's audio controller driver. You can try downgrading to an older driver or removing all audio devices under "Sound, video, and game controllers" in Device Manager and then rebooting.
