On some systems, then a bug within the audio driver has been identified, that causes only ICE Igloo Core Engine to output audio, blocking the audio from other apps. This issue is caused by the audio driver, forcing the audio device to enter exclusive mode, when ICE Igloo Core Engine is registering the installed ASIO devices. This issue is not depending on whatever an ASIO audio device is installed or not.
For multiuser systems, where multiple users is logged in at the very same time, then it’s recommended to disable the ASIO interfaces as stated below. Using ASIO audio devices in setup’s like these, then ICE Igloo Core Engine can crash - due to the exclusive nature of ASIO.
For systems, where this issue is happening, then open the audioSettings.xml. Go to the <output> tag, and change the attribute disableAsio=”0” to disableAsio="1". This will force ICE Igloo Core Engine to only use the Windows WASAPI audio devices, by disabling the ASIO devices in ICEIgloo Core Engine.
