October 31, 2025by Levit8 IT Solutions

Quick Device Checks

Ensure no other app is using the camera/mic (close web browsers with active meetings).
Unplug/replug USB headsets or webcams; try another port.

Windows Settings

Settings → Privacy & security → Camera/Microphone → allow apps to access.
Sound settings: select the correct Input/Output device and test.

Microsoft Teams

Settings → Devices: select your speaker, mic, camera; Make a test call.
Sign out/in if devices don’t appear; update Teams.

Zoom

Settings → Audio/Video: test devices; uncheck Automatically adjust mic if volume pumps.
In-browser joins may block devices, prefer the app.

Network & Quality

Switch from 2.4GHz to 5GHz Wi-Fi if possible.
Stop large downloads/OneDrive syncs during calls.
Use headsets to reduce echo.

When to Call IT

Corporate device policies block camera use.
Drivers missing in a VDI or restricted environment.

Levit8 can standardize conferencing gear and QoS so meetings “just work” across Teams and Zoom.
