I have creature speakers for my ibook, and an isub and apple pro speakers for my powermac, however my headphone jack on my ibook, has some how become blocked not visibly, but i can't connect the creatures to my ibook, ( the cable just won't go into the headphone socket, no matter how hard i push) so they are now useless to my ibook, but what i want to know is can i use the creatures alongside my isub + pro speakers on my powermac, i don't think it can be done, but i'm open to suggestions
