The 15 inch MacBook Air M4 has a 12 MP Center Stage camera and a three-microphone array, and a camera or microphone that does not work for one app is almost always a permission. System Settings, Privacy and Security, Camera and Microphone list each app and a switch; turn the app on, then quit and reopen it. A green dot in the menu bar shows when the camera is in use, and an orange dot shows the microphone. If the camera shows a black picture, make sure no other app is using it:
The checks in more detail
Mac cameras serve one app at a time, so quit video apps and the Photo Booth or FaceTime window. Center Stage, Portrait mode and Studio Light are in Control Center, Video Effects, and a stuck effect can make the picture odd, so turn them off. Restart the Mac if the camera is not detected at all. The microphone has voice isolation modes in Control Center, Mic Mode, which can clip your voice, so try Standard. A camera that never works in any app needs Apple Support.
If a conferencing app shows your picture cropped, Center Stage may be following you, and the green dot's menu offers a quick toggle; also check the app's own video settings in case it is set to a virtual camera left by other software. The microphone array uses beamforming, so speak towards the laptop and keep fans and keyboards away from it. On a managed work or school Mac, a profile can block the camera or microphone for specific apps, and the Privacy list will not show why; ask the administrator to check the configuration profile in System Settings, General, Device Management before assuming a hardware fault.
The 15 inch Air's camera sits in a narrow bezel, and the screen's tilt decides what it sees: an Air propped on a lap points the lens up at your chin, and raising it to eye level with a stand or a stack of books gives a flattering, steady picture. Lighting from behind makes you a silhouette, so face the light source. Check also that Center Stage is not cropping you oddly in a small room, and that no sticker or privacy shutter is over the lens.
