I am attempting to connect an Altec Lansing 5.1 computer speaker system (http://support.dell.com/support/edocs/acc/ada995/trouble.htm#light) to a Panasonic TC-54PS14 (http://www2.panasonic.com/consumer-electronics/shop/Televisions/All-VIERA-Flat-Panel-HDTVs/model.TC-54PS14.S_11002_7000000000000005702#tabsection). The Altec speaker system only has male yellow/green/black input connection cables. It also has an SPDIF indicator light that lights up if a "digital signal is detected", but I don’t see a SPDIF or optical digital audio input connection on the speaker system. The Panasonic only has optical audio out. Would this adapter work? (http://www.hdtvsupply.com/digital-to-rca-audio-converter.html) Please help. Thanks.
