I just tried it again and on mine, even though it says "no magazine" on CD2, with the television on (not on mute BTW) and the DVD player providing the signal (no off air reception here) I get the television sound through the diabolical Sony.
So, all I can tell you is that mine works that way. You may need to raise the television volume, not sure if that might help.
I have never, ever, seen a more difficult and non intuitive system. I am very glad I almost never watch Television.
