Common issues

No window appears after starting the app​

OVR-DummyHeadMic starts without showing a window and sits in the Windows system tray (the notification area at the bottom right of the screen).

  • Click the OVR-DummyHeadMic tray icon to open the settings window. If you cannot see the icon, open the “^” in the notification area.
  • Right-click the icon to choose Open Settings or Exit OVR-DummyHeadMic.
  • The window's close button (×) does not quit the app; it returns the app to the tray. To quit, use the tray menu.
  • To start with the window visible instead of in the tray, add the -showwindow launch option.

No audio​

  • Check whether Audio route is Normal or VST bridge. Choose Normal if you are not using a DAW.
  • Check that the input device is the microphone you are using.
  • Check that the output device matches where your headphones are connected.
  • Check mute and volume settings in Windows and the app.
  • Check whether another app is using the audio device exclusively.
  • After changing devices, wait briefly for the audio engine to restart.

No audio reaches OBS​

  • These steps are for the Normal route. For VST bridge, check the DAW route.
  • Add Audio Output Capture, not “Audio Input Capture,” to OBS.
  • Select the same output device in OVR-DummyHeadMic and OBS.
  • Check that the OBS source and audio mixer are not muted.

The unprocessed and processed voices are both audible​

Mute the regular microphone input in OBS. Use only the Audio Output Capture that captures OVR-DummyHeadMic's output for your stream.

Cannot move the dummy head​

  • Check that SteamVR recognizes both controllers.
  • Hold left-hand X + right-hand A, or both A buttons, at the same time.
  • If VRChat camera sync is active, end sync temporarily to return to manual placement.
  • For another controller or custom binding, check the in-app binding names.

Dropouts or unwanted noise​

  • In Normal mode, try Dropout protection (ring buffer) under Audio device settings. Switching it restarts the audio engine.
  • For steady background noise, try noise reduction. Turn it off if it changes the character of your voice.
  • Check device connections and whether another app is using a device exclusively.

VST bridge does not connect​

  • Insert VOrbit Bridge in the DAW and rescan plug-ins if needed.
  • Set the DAW sample rate to 44.1 or 48 kHz.
  • If another app is using the bridge, end its bridge mode first.
  • See the VST bridge status guide for specific messages.

VRChat camera is not detected​

  • Check that OSC is enabled in the VRChat Action Menu.
  • Show the User Camera before pressing “Start.”
  • If you restarted VRChat or this app, press “Start” again.
  • Check that your firewall or security software is not blocking local communication, mDNS, or OSC.
  • If a message says OSCQuery could not start, check for a port conflict with another OSC receiver app.

Calibration does not complete​

  • Keep the camera level and move it slowly with the same hand.
  • During left-right movement, keep its orientation and height steady and move in a straight line once in each direction.
  • During orientation measurement, keep the position fixed and change only the camera's orientation.
  • Do not use the stick to move or turn while holding the camera.

Sync position is offset​

  • Check that the camera's selfie/outward-facing orientation has not changed since calibration.
  • Calibrate again after changing or reloading your avatar.
  • For portrait filming, set “Acoustic Camera Orientation” to “Portrait.”
  • Use Local Anchor, not World Anchor or Pin.
