Hi!
Does anyone else have the same issue in your organization?
To my knowledge, there are some factors which can cause this issue. One of the factors is the network connection. So please make sure your network is stable.
Besides, it recommends you try to change another device to see if this issue still persists. If this issue is only persists in specific device, please try to update the operation system and audio driver in your computer.
