Audio Switch Boxes Not Working With 360? Options

[synbios1978]

I have a set of Logitech Z-5500 (I think) speakers attached to my computer. (They have optical audio in at any rate). I also have a Recoton ADS1000 (cheap optical audio switch box). I have my computer going through it with no problems, my original xbox and ps2 can go through it with no problems, but the 360 will not send sound through it. I can plug the 360 directly into the speakers and it sounds great, but for some reason it will not work with the switch box. I don't have another switchbox here to test out if it would work with another one or not. If anyone can tell me if there's something else I can try or if someone else has it running through a switch box, I would greatly appreciate it.

Thanks,
