Hello, I have encountered some problems when using Go to training. My audience is usually 25-50 people, then the live broadcast time is about 2 hours. Then on the live broadcast side, our approach is to use 2 computers. The main computer Is responsible for the start event, and be responsible for the operation of the control panel and reply to chat, while the other computer is the MC, we will join as audience first, then the main computer will allow the host computer share screen permission, then the MC will share screen and control the screen, but we realize that, sometimes our audiences unable to hear the sound during the demo suddenly, but the audience colleague in the same internet environment is no problem, he needs to restart the computer or change the computer to solve this problem. Every training, a small group of audiences will have this problem. May I ask if there is any solution for this problem?
