In order to output multi-channel audio, an outboard audio interface must be used.

Green Hippo recommends the Motu 828x USB interface as a tested, and readily available product. In order to install the Motu, it must be designated as the default device and configured correctly:

  • Stop the Hippotizer Engine and Zookeeper
  • Run the included Motu Driver installer.
  • Goto: Hippotizer (C:) > Program Files(x86) > MOTU > Audio
  • Open MOTU Audio Console.
  • Change audio sample rate to 48k (not crucial but recommended).
  • Untick “Use Stereo Pairs for Windows Audio” .
  • Close MOTU Audio Console.
  • Plug in your MOTU 828x USB cable.
  • Goto: Control Panel > Sound
  • Select MOTU Analog and click Set Default.
  • Close Control Panel.
  • Launch Hippotizer

Other Windows compliant multi-channel audio devices should also work, though we do not test them. In every case, the device must be designated as the default playback device before starting Hippotizer.
