I have to apologise as I had only intended to lock the thread that had headed off in a non-topic direction but I inadvertently clicked the delete thread icon instead (I think the browser was still redrawing the window and positioned the icon where I'd clicked)
I was locking the thread with a suggestion that you start a new on-topic thread anyway - if you need to know more than the fact that the device you are looking for is "toslink"

PS maybe it was for the best anyway?
