#1681 Resolves issue where audio recordings have incorrect system and site labels in metadata. Adds synchronized to channel processing manager's start channel request method to ensure that each channel is configured and started sequentially to avoid chance that simultaneous traffic channel grants occurring across two separate systems get inter-mingled on configuration and startup.
