Step 9. Change the camera back to a perspective projection. Set the

Step 11. Select GameObject > Create Other > Camera from the main
menu. Rename it to SphereCam. This camera will become the viewing
camera automatically.
Step 12. Locate the Depth property in the SphereCam's Camera
component. If this property is larger than the depth for the Main
Camera, it will be the one that is drawn in the Game. Change the
depth for both cameras so that the SphereCam's depth is 1 and the
Main Camera's depth is 2. The Main Camera will take control again.
Step 13. Set the SphereCam's position to (0,0,0).
Step 14. Drag and drop the SphereCam onto Sphere in the Hierarchy

sources in the game environment and ensures that they play at
the right volume and in the correct speakers. To resolve the error,
remove the audio listener from the SphereCam.
