The Audio Settings window is opened via the toolbar Config > Audio Settings
Sources
Every audio capable Layer will show within the sources menu, where the volume and mute settings can be configured. These settings are also available within the Playback tab of the Layer.
Layer types which can contain multiple sublayers, such as Compositions or Clip Banks, will have an Audio Bus, providing independent audio controls for the Bus and its sources.
Channel Mappings
When audio sources are routed to the output device, the channel mappings dictate how the channels will be mapped. By default,
A 5.1 signal is routed to a 5.1 bus, as a 1:1 mapping
A 5.1 signal is routed to a stereo bus, by downmixing to stereo.
Output Device
ICE supports WASAPI and ASIO audio devices. Select the output device from the list.
