I have one set of speakers that I've owned for a long time. Recently I rigged them up in the bathroom so I could read a book while I take a bath. (Crazy huh?) The cable to plug it into the bookport has a connector with a shaft, longer than usual. I found that if I plug it in only part way, sound will come through both speakers. I have to position it so that contacts to both stereo sides are touching in the bookport jack. So, fooling around this way, you may be able to get your speakers to work okay.
