I just sold my iMac to my aunt for her business. I used the money to buy a new iMac, in case you were wondering. Well, she has these Creative Labs computer speakers that output SPDIF digitally. Well I didn't know that they wouldn't work when plugged into the headphone jack of the iMac. By the way the iMac is a 24" model from early 2009 running Snow Leopard. I told her I would figure out how to make these work that it had to be something easy. But honestly, I can't figure it out. What do I do? Can it be done? It seems silly that a modern computer couldn't output to these speakers, so it has to be capable. Please help me if you know what I need to do. Thanks in advance.
