As your issue description is primarily written in English, I will provide my response in English for your convenience. Please feel free to let me know if you would prefer the information in another language.

Hello,

Based on the images provided, it appears that Microsoft Teams is currently unable to detect any audio or video devices, as the Speaker, Microphone, Secondary ringer, and Camera fields are all showing"None". This can prevent Teams from making or receiving calls.

To help isolate the cause, please try the following steps:

1/ Test Teams in a supported web browser

Please sign in to Teams on the web using Microsoft Edge or Google Chrome and allow the browser to access your microphone and camera when prompted.

2/ Check whether Windows detects your audio devices

Open Settings > System > Sound.
Verify that a speaker appears under Output and a microphone appears under Input.
If the devices are not listed, open Device Manager and expand:
- Sound, video and game controllers
- Audio inputs and outputs
Ensure that no devices are disabled.
In Device Manager, select View > Show hidden devices, then choose Action > Scan for hardware changes.

3/ Review Windows privacy permissions

Navigate to Settings > Privacy & security > Microphone and confirm that the following settings are enabled:

Microphone access
Let apps access your microphone
Microsoft Teams (work or school)
Let desktop apps access your microphone

If these options are already enabled, try turning them off and back on, then restart your computer.

You should also review Settings > Privacy & security > Camera and ensure that Microsoft Teams is allowed to access the camera.

4/ Clear the Teams cache

Please completely exit Microsoft Teams, including closing it from the system tray, then clear the Teams cache and restart your device before opening Teams again.

You can follow the guidance in the Microsoft documentation: Clear the Teams client cache

Hopefully, these steps will help resolve the issue. If the problem persists, please let me know whether the audio devices are visible in Windows Sound Settings and whether the same issue occurs when using Teams on the web. This information will help narrow down the root cause.

Hi,

Thank you for confirming the results of the previous troubleshooting steps.

Since the audio devices work correctly in Teams on the web and are also detected by Windows, the issue appears to be limited to the Teams desktop application rather than the audio hardware itself.

As the next step, please make sure that both Teams and Windows are fully updated. Then completely exit Teams from the Windows notification area and close any other applications that may be using the microphone or speaker, such as Skype, Zoom, Webex, browser tabs, or audio-management software. After that, disconnect and reconnect the audio device, reopen Teams, and check Settings > Devices again.

If you have multiple work or school accounts connected in Teams, please also try signing out of the additional accounts and restarting Teams with only the affected account signed in.

If the microphone and speaker become available under Settings > Devices, select Make a test call to verify that Teams can access them correctly.

If the devices are still missing only from the Teams desktop application, please contact your IT administrator. They can review the Teams client configuration, collect the relevant diagnostic logs, and open a support request with Microsoft Support if further investigation is required. In the meantime, you may continue using Teams on the web as a temporary workaround.

I understand how inconvenient this issue can be, and I hope the suggested steps help. Please let me know how it goes, and I will be happy to assist further.

Warm regards.
