It's the most British of small disasters: you join a Teams call from your kitchen table in Leith, click the camera icon, and nothing happens. Or your microphone shows the right name in Zoom but everyone tells you they can't hear a thing. Webcam and microphone faults on Windows 10 and Windows 11 are one of the most common issues we see at our Edinburgh workshop — and the good news is most of them can be fixed in a few minutes once you know where to look.
This guide walks through the checks we run on every machine that comes in for a "camera not detected" or "mic not working" complaint, in roughly the order that catches the most faults the fastest.
1. Check the Privacy Settings First
Before you start blaming drivers or hardware, open Settings → Privacy & security → Camera (and the Microphone page beneath it). Make sure two switches are turned on: Camera access at the top, and the per-app permission for whichever app you're using — Teams, Zoom, Chrome, Edge, Discord, OBS, and so on.
This is, by a long way, the most common cause we see. After a feature update Windows often resets these toggles silently, especially on machines we've upgraded with a clean Windows install. If your camera worked yesterday and is dead today, start here.
2. Make Sure the Right Device Is Selected
Most laptops have a built-in webcam and an internal microphone, and many users in places like Morningside and Stockbridge work from home with a separate USB headset or a desk camera as well. Windows doesn't always pick the device you want.
In Teams, click the three dots near your tile during a call and choose Device settings. In Zoom, open Settings → Audio and Settings → Video. Pick the correct microphone and camera by name. If you only see "Default" listed, plug the headset back in and try again — Bluetooth devices in particular sometimes need to be reconnected before Windows shows them as an option.
3. Look for the Hardware Privacy Switch
Many modern laptops — Lenovo ThinkPads, Dell Latitudes, HP EliteBooks — have a physical webcam shutter or a function key that disables the camera at the hardware level. Look along the top of the screen for a small slider, and check your F-keys for an icon that looks like a crossed-out camera. If the camera is muted in firmware, no amount of software fiddling will turn it on.
4. Reinstall the Driver from Device Manager
If permissions and device selection are correct, the driver is the next suspect. Right-click the Start button and open Device Manager. Expand Cameras and Audio inputs and outputs. Right-click your webcam and microphone and choose Uninstall device — tick the box to remove the driver if it's offered. Restart the PC and Windows will reinstall a fresh copy automatically.
For built-in laptop cameras, it's often worth grabbing the latest driver from the manufacturer's support site (Dell, HP, Lenovo, ASUS, etc.) rather than relying on Windows Update. We've seen flaky webcam behaviour on machines from Bonnyrigg to Penicuik that cleared up immediately after a manufacturer driver was installed over the top of the generic one.
5. Run the Built-In Troubleshooters
Windows 11 has dedicated troubleshooters for both audio and video. Open Settings → System → Troubleshoot → Other troubleshooters, and run Recording Audio and Camera. These automate the most common driver and service checks — not glamorous, but they fix a surprising number of cases on their own.
6. Test in a Different App
Open the built-in Camera app and the Sound recorder app from the Start menu. If both work there, the fault is inside Teams or Zoom — usually a stuck sign-in, a corrupted cache, or an update waiting to install. Sign out, restart the app, and try again. If neither works in the built-in apps either, it's a system-level issue worth digging into properly.
7. USB and Cable Faults
External webcams and headsets are often the problem rather than Windows. Try a different USB port — ideally one directly on the PC rather than through a hub or a monitor's USB pass-through. Swap the cable if you can. If you have a USB device that isn't being recognised at all, that's worth checking too. We've fixed countless "broken" microphones in Portobello and Musselburgh that turned out to be a tired USB cable.
8. When It's Genuinely a Hardware Fault
If you've been through every step above and the camera or microphone still doesn't show up at all in Device Manager, the hardware itself may have failed. Built-in laptop webcams use a thin ribbon cable that runs through the screen hinge — a known weak point on machines that get opened and closed many times a day. Internal microphones can fail after liquid spills or board-level damage.
That's where we come in. Our laptop repair service covers webcam and microphone replacements on most major brands, and our software troubleshooting service handles the deeper Windows-side problems that won't budge with the usual fixes. For business users with a fleet of machines, our business IT support can sort recurring camera and audio issues across your team in one visit.
