A bug introduced in v5.5.7 which could cause a few samples of audio to play at the incorrect volume at the beginning of playback.

Changing the "Enabled" checkbox in a Cue Output or Device Output audio effect window now correctly updates the effect widget checkbox.

The "inverted" property of Network cue and audio map background images is now initialized correctly on collaborator machines.
