so Charset Audio says it can connect to speakers using MCMultipart 2
i have the audio cables but they dont connect to anything

Audio Transport - if MCMultiPart 2 is installed, it provides Audio Cables which allow you to connect audio players, recorders, speakers, etc. together.

i looked online and supposedly they are suppose to connect to jukeboxes but the cables don't even connect to jukeboxes so is there another mod which adds speakers or is this just not implemented
