Trying to connect a Bose Wave Radio as external speakers for a 24" Sony set. I tried using the mini plug connection on the back, but could never get the TV to accept the radio as an auxiliary amplifier. Then I tried the headphone jack on the left side of the set, and it doesn't seem to have any output. The set recognizes that something is plugged in, and shows the supposed headphone volume onscreen, but there is no signal. No sound when I plug in a set of earbuds either. Am I missing a setting somewhere?
