ICE supports WASAPI and ASIO audio devices. Select the output device from the list.
Please notice: On some systems, then a bug within the audio driver has been identified, that causes only ICE 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 is registering the installed ASIO devices. This issue is not depending on whatever an ASIO audio device is installed or not.
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 to only use the Windows WASAPI audio devices, by disabling the ASIO devices in ICE.
