spdif and analoge out at the same time

Hi guys

Today I recieved a USB sound card for my laptop so i can hook it up digitally to my AV reciever (Fantastic by the way): http://www.turtlebeach.com/site/prod...udioadvantage/

It has one 3.5mm (headphone) jack which outputs digital (optical) and analogue at the same time. A couple of days ago I found this adapter that seperates the two signals so you can listen to them at the same time, but now I cant for the life of me find it again :mad:

I want to get this adapter so I can avoid constant switching/wear and tear between my pc speakers and the optical connector to the reciever.

Have any of you lot heard of such a product/think I was hallucinating??

Thanks
Tim
