I would like to know if there are open source (read 'free') or other alternatives that would allow multiple simultaneous playlists played through the myriad of audio interfaces out there. The line outs are then plugged into a CobraNet matrix, which handles the distribution of the music/sound to their respective areas. I'm looking at eight channels minimum, timed playlist start/stops, and triggered announcements. So far the only software and hardware I've found are proprietary broadcasting solutions which tend to be a bit heavy on the wallet or meant for home use."
