Quick answer
If others can't hear you, first check whether the microphone is even on and whether the right device is selected in the app. Then check system permissions, the sound level in the operating system, and whether the microphone is physically muted or being used by another app. In most cases the problem is solved by selecting the correct microphone and granting permission.
How to recognize the problem
- Others say they can't hear you or that you sound faint
- The microphone indicator in the app doesn't react to speech
- The microphone works when recording but not on a video call
- The sound is only heard occasionally or with noise
- The app shows a microphone error
Most common causes
Wrong microphone selected
The app is using a different device from the one you're speaking into, for example the camera microphone instead of the headset.
Microphone is off or muted
The mute button in the app or a physical switch on the headset is turning off the sound.
Missing permissions
The system or browser is blocking access to the microphone, so the app isn't getting any sound.
Device busy or faulty
Another app is using the microphone or the driver is faulty, so the sound isn't reaching the call.
Low input sound level
The microphone gain in the system is turned down or the microphone is too far from your mouth.
Step-by-step fix
- 1
Check whether the microphone is on
In the video call app, find the microphone icon and make sure it isn't crossed out. If it is, click it to turn on the microphone. On your headset, check the physical mute switch.

If nothing helps
If you've checked everything listed and others still can't hear you, try another microphone or headset. Sometimes the problem is with the device itself or the network. If you're using a VPN or a corporate network, check whether the network is restricting audio transmission. As a last resort, contact IT support and state which device and app you're using, which steps you've taken, and whether the problem occurs in all apps or just one.
How to prevent it
- Before every meeting, check the microphone selection in the app.
- Regularly update drivers and the operating system.
- Use a headset with a microphone and check the physical switch.
- Allow microphone access only to the apps you use.
When to call a professional
If you've checked all the steps and the problem repeats in multiple apps, or you suspect a microphone fault, contact IT support. They can test the device and network in more detail.

Why can they hear me in one app but not in another?
The app where they can't hear you probably has the wrong microphone selected or hasn't been granted access. Check the device selection and permissions in that app.
How do I know whether the microphone is even on?
In the app, look at the microphone icon: if it's crossed out, click it. In the system, check the input sound level while you speak; if it doesn't change, the microphone isn't picking up sound.
Could it be a network problem if they can't hear me occasionally?
It could be. A poor connection can cause audio dropouts. Check your internet speed and stability, and use a wired connection if possible.
