Fixing camera and microphone problems in Teams
Updated 10 November 2026 · How-to
Nobody can hear you, or your camera is black? Quick checks for Teams meetings, from the right device to privacy settings.
Most Teams audio and video problems come down to Teams using the wrong device, or the computer blocking it from using the camera or microphone. A few quick checks usually sort it out, ideally before the meeting starts.
Test before you join
When you join a meeting, Teams shows a preview screen. Check that your camera image appears and that the microphone bar moves when you speak. You can also make a test call any time: click the three dots next to your profile picture, open Settings, then Devices, and choose Make a test call.
Choose the right device
If you have a headset, a docking station, a second screen with speakers or a webcam, Teams may pick the wrong one. In the meeting, click More and then Settings and Device settings, or the arrow next to the microphone and camera buttons. Then select the speaker, microphone and camera you actually want to use. Plugging in a headset after the meeting starts can also confuse it; choose the headset again in the same place.
Check the mute and privacy switches
Many headsets have a mute button on the cable or earcup, and many laptops have a camera shutter or a keyboard key that turns off the camera. On Windows, also check Settings, Privacy and security, then Camera and Microphone, and make sure access is allowed for Teams. On a Mac, check System Settings, Privacy and Security.
Close other apps
Only one app can use the camera at a time on some computers. Close Zoom, a browser tab with another meeting, or any camera app, then leave and rejoin the Teams meeting.
Echo and poor sound
Echo usually comes from someone using laptop speakers with the microphone turned on. A headset fixes it. Choppy sound and frozen video usually point to the internet connection; turn off your video to save bandwidth, move closer to the Wi-Fi access point, or see Fixing slow or dropping Wi-Fi.
Still stuck
Join from your phone with the Teams app so you do not miss the meeting, then email hello@bitlogix.tech afterwards and we will fix the computer.
