Check your controller bindings

VR button names depend on your SteamVR controller bindings. This app's How to use page displays the binding names it can read for step 3 (placing the dummy head) and step 5 (toggling spatial audio). Check that display first.

Typical Quest-style controller bindings are:

Action	Typical buttons
Follow the right hand to place the dummy head	Hold left X + right A, or both A buttons
Toggle spatial audio	Press left Y + right B, or both B buttons

Other controllers may use different button names. If the app's display does not match your controller, check this app's controller binding in SteamVR. When the app cannot read a binding name, it may keep the default example text.

Turn the wrist menu on or off and select its hand under Main settings. Use the wrist icon to open it. The menu may be hidden while the SteamVR dashboard is open. See common issues if it does not appear.
