1. It doesn't work with the meeting/video service I'm using
We've tested the camera and had it working with Zoom, Hangouts (Meet) and Skype - unfortunately, we can't guarantee it'll work on other services (such as Discord or others).
2. No audio - the Microphone isn't working
Sometimes the Raspberry Pi might fail to register the camera's built-in microphone. A simple fix for this is to only plug in the webcam into a USB port once your Raspberry Pi has fully booted.
Also make sure the microphone is the selected device for voice input.
3. No video on Zoom or another service
Sometimes this is simply a case of going to the meeting settings (bottom left at the time of writing) and making sure that the video and microphone devices are correctly set to use the webcam. Sometimes they will default to other devices, especially when using this with Windows. Also, try fix number 2 (above).
4. No video or disconnections/poor performance
This is usually related to power issues. Make sure you're using an official Raspberry Pi power supply, as these quality supplies can provide enough power for both your Raspberry Pi and the webcam.
Please don't power your Pi from a computer or other device's USB port - they're usually not up to the job.
If you have lots of other USB devices attached to your Raspberry Pi they may all be fighting for power. Try removing all other USB devices.
