Larry got a new Panasonic TV, but it has no analog audio out capability. He has powered speakers and amp that he can plug into, but he has to convert that digital audio signal to analog first. He has a preamp and converter, but it only works if he routes it through the VCR. Leo says this is the reason that people who want home theaters systems buy AV receivers. They can convert and drive multiple sources.
Larry will need a Digital to Analog audio converter to run it straight into his speakers. Monoprice has one that works great for $22. That chatroom says to also make sure the TV is sending unencoded audio.
