If you encounter issues when switching audio or video devices or encounter errors when attempting to join a conference due to an audio or video device, please try the following:
Try changing your audio or video device to another device and see if it works
Try unplugging and replugging your device
Try exiting and re-entering the conference
Confirm that another app is not already using your audio or video device, especially on Linux
Confirm that you are not muted. On Windows, you may need to open the "Volume Mixer"
Try restarting your computer
If you still encounter issues, please email email@example.com and we'll work with you to debug.
