Troubleshooting Logitech C925e microphone not working in video calls
Applies to: Logitech C925e Business Webcam
Last updated: 20 November 2025
Problem
Your Logitech C925e webcam appears to work for video, but nobody can hear you in meetings. In Zoom, Microsoft Teams, Google Meet or other apps, your voice is silent, very quiet or distorted. The C925e microphone might not show up as an input device, or it appears in the list but the level meter does not move when you speak.
Solution
When the Logitech C925e microphone is not working, the most common causes are app permissions, the wrong input device selected in your calling app, system privacy settings, audio being muted in the app, or another device taking priority. By checking your system sound settings, granting microphone permissions, selecting the C925e in your meeting app and testing input levels, you can usually restore audio quickly.
Step by step instructions
1. Confirm the microphone is recognised by the operating system
On Windows 10 and Windows 11
- Right click the Start button and select Settings.
- Go to System > Sound.
- Under Input, check the drop down list of devices.
- Look for Logitech C925e (or a similarly named device).
- Select it, then speak in a normal voice while watching the Input volume level meter.
- If the bar moves when you speak, Windows is receiving audio from the C925e. If not, try unplugging and reconnecting the webcam and selecting it again.
On macOS
- Open System Settings (or System Preferences on older versions).
- Go to Sound > Input.
- Look for Logitech C925e in the list of input devices.
- Select it, then speak and watch the input level meter.
- If the meter moves, the Mac can hear the C925e microphone.
If the microphone does not appear at all in the system list, there may be a USB connection issue, a driver problem or a hardware fault. In that case, work through USB troubleshooting and test the webcam on another computer if possible.
2. Check microphone privacy and app permissions
Windows microphone privacy settings
- Open Settings and go to Privacy & security.
- Click Microphone.
- Make sure Microphone access is turned on for the device.
- Ensure Allow apps to access your microphone is turned on.
- Scroll down and confirm that your key apps, such as Zoom, Microsoft Teams and your browser, are allowed to use the microphone.
macOS microphone permissions
- Open System Settings and go to Privacy & Security.
- Click Microphone.
- Ensure that your meeting apps and browsers are enabled.
- If an app is not ticked, tick it and then fully quit and reopen that app.
If permissions were previously denied, your meeting app may have been silently blocked from using any microphone, including the C925e.
3. Select the C925e microphone in your meeting app
Even if the system recognises the C925e, your meeting app may still be using another mic.
Zoom
- Open Zoom and click your profile picture, then choose Settings.
- Go to the Audio section.
- Under Microphone, choose Logitech C925e from the drop down list.
- Speak and confirm that the input level bar moves.
- Untick Automatically adjust microphone volume if it is over correcting and making you too quiet, then adjust the level manually.
- In the main Zoom window, during a call, click the arrow next to the microphone icon and confirm Logitech C925e is selected there as well.
Microsoft Teams
- Open Teams and go to Settings > Devices.
- In the Microphone section, select Logitech C925e.
- Speak and confirm the level indicator moves.
- Use Make a test call (where available) to listen to a short recording of yourself using the C925e mic.
Google Meet (browser)
- In a Meet call, click More options then Settings.
- Select the Audio tab.
- Under Microphone, choose Logitech C925e.
- Speak and check that the input level indicator moves.
- If prompted by the browser to allow microphone access, choose Allow.
4. Make sure you are not muted in multiple places
It is easy to be muted in more than one place at once.
- Check the mute icon in your meeting app. Make sure it shows that your microphone is on.
- On some keyboards and laptops, there may be a physical microphone mute key or indicator light. If there is a mic icon key, press it to toggle.
- In Windows, in the notification area, check if there is a global mic mute or privacy control supplied by your antivirus or endpoint protection software.
- If you use a headset at the same time, make sure the headset’s own mute switch is off.
- After confirming all mutes are off, speak again and watch the input level meter.
5. Adjust microphone levels and background noise controls
If people can hear you but say you are very quiet or cutting in and out, the level or noise controls may need tweaking.
On Windows
- Open Settings > System > Sound.
- Under Input, select Logitech C925e then click Device properties or Microphone properties.
- Increase the input volume slider to a comfortable level while watching the meter.
- Avoid setting the level too high, which can cause distortion and clipping.
In meeting apps
- In Zoom, adjust the Input Volume slider while watching the meter.
- Reduce aggressive noise suppression settings if they cut off the start or end of your words.
- In Teams, you can toggle noise suppression levels under Settings > Devices.
- If noise suppression makes you sound choppy, lower it or turn it off temporarily for testing.
6. Check for conflicts with other audio devices
Sometimes another device steals focus or your app switches to it automatically.
- Disconnect USB headsets or microphones temporarily and test with only the C925e connected.
- In Windows Sound settings or macOS Sound settings, remove or disable unused audio devices if they are no longer needed.
- Close any software that may be using another microphone at the same time, such as voice recording tools, streaming software or virtual audio cables.
- Restart your computer after removing conflicting devices, then select the C925e microphone again in your meeting app.
7. Consider managed devices and security tools
On work or school devices, security policies can limit microphone access.
- If your device is owned by an organisation, check with your IT team whether microphone use is restricted.
- Ask if any endpoint protection or privacy tools are controlling microphone access and could be blocking the C925e.
- If they adjust policies, restart the device and retest the microphone in a simple app like the system voice recorder before trying a full meeting.
Optional methods or tools
- Test recording with a basic app
- On Windows, use the built in Voice Recorder app to make a short test recording with the C925e microphone selected.
- On macOS, use QuickTime Player, choose New Audio Recording, and pick the C925e as the input.
- Playback will tell you clearly whether the mic is working outside of meeting apps.
- Use Logi Tune for quick checks
- Open Logi Tune and select the Logitech C925e.
- Use any built in test options to confirm the device is detected and to see input activity.
- This can help separate app specific issues from basic hardware problems.
- Fallback to another microphone if needed
- If the C925e microphone remains unreliable in a particular setup, you can still use the webcam for video and switch to a USB headset or desk microphone for audio, then revisit troubleshooting later.
Best practices or tips
- Decide whether you want to use the C925e microphone as your main input or only as a backup. Set that choice consistently in your operating system and meeting apps to avoid confusion.
- Before important calls, open your meeting app’s audio settings and run the built in test tools so you can fix any sound issues before joining.
- Keep a simple headset nearby as a backup audio device. If you have difficulties mid call, switching microphones is faster than deep troubleshooting while others wait.
- After operating system updates or changes to privacy settings, recheck your microphone permissions and selected devices, as updates can sometimes reset preferences.
- Avoid changing default audio devices constantly. Pick a primary combination of camera and microphone for your main workstation and keep it stable.
Reliable audio is just as important as clear video when you are using the Logitech C925e for business calls. Once you work through system recognition, privacy permissions and correct device selection in your meeting apps, most microphone issues are resolved without needing new hardware. The key steps are making sure your computer can see and hear the C925e, then telling Zoom, Microsoft Teams or Google Meet to use it and confirming there are no extra mute switches in the way.
If the microphone still does not work after following this guide and testing on another device, you have a clearer picture of where the problem lies. You can then decide whether to replace the webcam, rely on a dedicated microphone, or engage your IT team if this is a managed device. Having a simple checklist to follow makes it much easier to get your C925e audio working again and reduces stressful last minute troubleshooting before important meetings.
