• Some antivirus software can interfere with certain iVGA PRO features. In such cases, try disabling your protection briefly. If the problem goes away, consider using a different anti-malware product.
  • If iVGA PRO’s connection to TriCaster seems intermittent, make sure only one network path exists between the two systems, to prevent the PC from switching back and forth between connections.
  • In some cases, the use of headphones or other audio hardware may disable or hijack standard system audio output. You can sometimes resolve this issue by simply unplugging the headphones. In other cases, third party audio drivers that have been installed do not support
  • Some systems and third-party audio device drivers deliberately restrict access to system sound (for DRM reasons), preventing their output from appearing as an audio source option for iVGA PRO. Several workarounds exist.
    • You could simply loop an audio cable from the system’s output back to an input, and select that input as the audio source for iVGA PRO.
    • Often you may be able to select a different audio device (such as “Stereo Mix” or “SoundMAX”) as the system default. Right-click the ‘speaker’ icon at right in your Windows® Desktop taskbar, and select “Recording Devices”.  This opens the audio device control applet, allowing you to choose among those available.  (It is sometimes useful to right-click in this pane and enable “Show Disabled Devices”, as well.)
    • Other third-party software solutions exist as well. An Internet search for terms like “audio loopback software” or “virtual audio cable” will turn up relevant links.
