Logitech 5.1 Game Console Adapter/TV - SoCal
 

Used this on my old TV to use my Logitech computer speakers, will work with any system that uses 3.5 connections. Went to optical on my new TV so don't need this anymore. Looking for $10 shipped. Not just for games either as the title can be misleading. I used the adapter for just watching TV and movies as well.

I can throw in the RCAs and 3.5 bundle for another $5.
