Improved: For playback devices, the APO is now installed as a GFX (Post-mix) APO, so only one instance of Eq. APO is running for any number of applications. Existing LFX APO installations are upgraded by the Configurator (shown as "APO will be upgraded").

Added: Support for installation to capture devices. They can be selected on a second tab in the Configurator.
