3. Unable to hear or selecting the correct Mic input

If your group is unable to hear you talking it could be because you have not selected the right input on the SynthesisVR Voice Chat service:

  1. Click the Voice icon on your taskbar and then click the Mic Icon
  2. Select the correct Mic input

4. Seeing weird characters and non-sense text inside the voice chat app on the VR stations

 The Voice Chat server built into the SynthesisVR Server Mode have a local SQLite database. As long as this database doesn’t keep any important data, it is still used to control the status of the “calls”. If the server is restarted or shut down at the same time when we are saving data in the local database, then that database file may got corrupt.
To fix this issue, perform the following actions on your VR Server PC:

  1. Stop the “VR ServerMode”
  2. Delete the directory: C:\ProgramFiles\SynthesisVR\Operator\db
  3. Start the “VR ServerMode”

Then, on the VR stations, stop and start the Voice Chat. It should connect properly.
