Cisco Webex is widely used for online meetings, virtual classrooms, and business communication on Windows 11. When the microphone is not working in Webex, other participants may not be able to hear you, or Webex may fail to detect any audio input at all. This can disrupt meetings and prevent effective communication.
This issue often occurs due to incorrect microphone selection, blocked permissions, muted system input, or conflicts between Windows audio settings and the Webex app. In many cases, the microphone itself is functioning correctly, but Windows 11 or Webex is not configured to use it properly.
Fixing microphone issues in Cisco Webex on Windows 11 requires checking both system-level audio permissions and in-app audio settings. The steps below outline reliable methods to restore microphone functionality and ensure your voice is captured correctly during meetings.
How to Fix Microphone Not Working in Cisco Webex on Windows 11
The methods in this section focus on resolving permission, configuration, and device selection issues that commonly prevent Cisco Webex from accessing the microphone. Apply each method carefully and test the microphone after completing a step.
Restart Webex or the system where instructed so changes take effect properly.
1. Check Microphone Selection in Cisco Webex
Webex may be using the wrong input device.
- Open Cisco Webex.
- Click Settings or Audio & Video from the app menu.
- Under the Microphone section, select the correct microphone device.
- Speak into the microphone and verify that the input level moves.
- Save the changes and rejoin the meeting if necessary.
Selecting the correct input device ensures Webex captures audio from the intended microphone.
2. Allow Microphone Access in Windows 11 Privacy Settings
Windows 11 may block microphone access for desktop apps.
- Press Windows + I to open Settings.
- Go to Privacy & security.
- Select Microphone.
- Turn on Microphone access.
- Enable Let desktop apps access your microphone.
- Ensure Cisco Webex is allowed.
This allows Webex to use the microphone at the system level.

- Open Cisco Webex.
- Go to Settings > Audio & Video.
- Click Test microphone.
- Speak and listen for confirmation that audio is detected.
Running the audio test helps identify whether the issue is app-related or system-related.

Only one app can fully control the microphone at a time.
- Close apps such as Teams, Zoom, Skype, or recording software.
- Press Ctrl + Shift + Esc to open Task Manager.
- End background processes that may be using the microphone.
- Restart Cisco Webex and test again.
Removing app conflicts allows Webex to access the microphone properly.
6. Update or Reinstall Audio Drivers
Outdated or corrupted drivers can cause microphone issues.
- Press Windows + X and select Device Manager.
- Expand Sound, video and game controllers.
- Right-click your audio device and select Update driver.

- Restart the app after updating.
Keeping Webex updated ensures compatibility with Windows 11 audio systems.
Final Thoughts
A microphone not working in Cisco Webex on Windows 11 is usually caused by incorrect permissions, wrong device selection, or audio conflicts rather than a faulty microphone.
