Mid-lecture, my audio/video feed cut to black. I was still able to interact with the class via the Chat box. The students could not hear or see me. I could see, but not hear, the students. When I tried to change the audio input through CampusWire, the interface would not let me unmute myself. All of the following methods failed: 1) fully closing my browser and restarting. 2) Asking students to all leave and rejoin the class. 3) Changing microphones and cameras completely. 4) Having everyone turn their cameras. I was successful in restarting lecture only after fully restarting my desktop and creating a new live room. However, this only lasted 5 minutes before the issue repeated itself. Help.
