Vizio Soundbar question:
I'm going to pick up a 40" Vizio soundbar later this week (just the bar not the wireless sub). Anyway I believe I need an optical cable to hook it up correct? Are all these optical cables pretty much the same (like HDMI cables) I see you can pick up an optical cable a lot cheaper online than at the store (just like HDMI cables).
Just wondering what everyone else is doing? Also how long does the cable need to be?
