Troubleshooting

1. The web conference audio and or video is not outputting to the in-room devices.
   1. Check the in-room equipment and make sure it is powered on.
   2. Check the ScreenBeam Conference connection from the laptop to ScreenBeam receiver, verify that Conference mode is enabled.
   3. Check the device settings in your web conferencing application.
   4. Check the output volume setting from the laptop.
2. The in-room audio or video stops working in the middle of a web conference meeting.
   1. Check the device settings in your web conferencing application.
   2. Check the on-screen message from ScreenBeam receiver.
   3. Try reconnecting from ScreenBeam Conference application.
   4. Restart ScreenBeam receiver and reconnect if the issue persists.
3. The web conferencing audio and or video quality through the in-room equipment is not smooth.
   1. Make sure the system meets the minimum hardware requirements.
   2. Make sure the system CPU resource is not overloaded by other applications.
   3. If using Wi-Fi Miracast for connection, make sure to select a clear wireless channel for Wi-Fi Direct P2P.
   4. If using Wi-Fi Miracast over Infrastructure, make sure the laptop has a solid Wi-Fi signal strength of 85% or better, connection to an AP on a 5GHz channel is strongly recommended.
   5. Restart ScreenBeam receiver and reconnect if the issue persists.
4. The ScreenBeam Conference and or mirroring randomly disconnects.
   1. Make sure your operating system receives the latest updates.
   2. If using Wi-Fi Miracast over Infrastructure, make sure the laptop maintains a solid Wi-Fi connection and does not fluctuate or roam between APs. Windows may falsely detect the system/user is walking away and trigger an auto-disconnect.
   3. If the issue persists, contact your Microsoft representative, and voice the opinion about Windows native screen mirroring.
5. The remote participants hear echo of their own voice when speaking.
   1. If the deployment configuration consists of the USB camera and the TV speakers, then this is expected. ScreenBeam Conference does not support this model currently.
   2. If this deployment configuration is temporary for testing, the following steps could apply:
      1. Avoid placing the camera (with microphone) or microphone next to the speaker
      2. Avoid facing the camera (with microphone) or microphone towards the speaker
      3. Adjust the TV speaker or soundbar volume to 40% or less
      4. Adjust the user device laptop volume to 80% or less
      5. Reduce the microphone volume from 100% if needed
6. The microphone volume, from the USB camera or USB speaker, is too low.
   1. Verify the microphone in the OS audio settings is not muted
   2. Increase the microphone volume in the OS audio setting if necessary
   3. Check the device’s microphone alone by connecting it directly to the PC to verify the issue is not hardware specific
   4. Check the device’s manufacturer website for the latest firmware and update it
