Declare the output chain via services.easyeffects.extraPresets and load it with preset.output, replacing the GUI-only configuration that did not survive the tmpfs root. autogain target is set to -12 dB (EasyEffects defaults to -23, which is too quiet for playback); the limiter acts as a transparent -1 dB safety net via threshold=-1 and gain-boost=false.
