The webcam and microphone on a Nitro V15 fail for software reasons far more often than hardware ones. If an app says no camera is found, check Windows privacy settings first: Settings, Privacy and security, Camera must allow apps to use the camera, and the same for the microphone. Then check that the camera appears in Device Manager under Cameras; if it is missing, install the camera driver for your model from Acer's page. Many Acer laptops have a function key or a privacy setting that disables the camera, so check that too.
For a microphone that is quiet or picking up nothing, open Sound settings, choose the microphone in Input and run the test, and turn off Audio enhancements, which owners found muffled voices in calls. A webcam light that never comes on in any app points at a hardware fault. Test the camera in the Windows Camera app first, because if it works there the problem is the other app's permissions or settings, and if it fails there the problem is Windows or the hardware. Video call apps also have their own camera selection menu, which sometimes points at a virtual camera left by other software.

Model-specific
What is true of this model and not of its siblings
- Privacy first
- Windows blocks camera access by default in some setups.
- Muffled voices
- One owner traced muffled audio to enhancement settings.
- Virtual cameras
- Software such as capture tools installs a virtual camera that can steal the selection.
- Microphone array
- The Nitro uses a built-in microphone, and a muted key or a low input level makes voices faint.
- Privacy shutter
- Some models have a shutter or a function key, so look at the keyboard icons.
Stop boundary
When this stops being a self-service repair
- !If the camera is missing after the driver reinstall, contact Acer
