Connecting HDMI to 5.1 channel 3.5 mm audio
I recently bought a $60 Logitech surround speaker set from Best Buy, and I'd like to get it hooked up to my Blu-Ray player. Here's what I have to work with:
Speaker set: three 3.5 mm inputs, green, black, and orange
LG BD640 Blu-Ray player: HDMI out, RCA L/R out, digital audio coax out
Vizio E420VT HDTV: SPDIF optical out, 3.5 mm stereo out
Is there a relatively inexpensive way to make this work, or would it be better to return the speaker set and get a different system? I've looked at HDMI audio extractors, but those seem to be out of my price range.
