Move the speakers
Move the speakers away from the microphone. Additionally, ask the video call contact to adjust the speakers that the contact uses.
Disable the microphone
If you use the camera microphone or the headset microphone, disable the other microphone that you are using, or disable line volume. To do this, follow these steps.

Check the laptop power connection
If you are using a laptop that is currently connected to AC power through the power adapter, determine whether the power connector is still causing the static:
Unplug the power adapter and use the laptop battery to run the laptop. If the static issue persists even when the laptop runs on battery, you may have to service the laptop.
If there is no static issue when the laptop runs on the battery, try to connect the laptop a different plug in a different room or building. For example, try to connect the laptop power adapter in an office or in a friend's house. This is to determine whether the power sockets in your house have leakage.
