I think that the multiple audio jacks in the SB's are galvanically the same
point, so, if I'm not wrong, what you are doing is shorting the CD audio
outputs. Certainly, it works, since there must be some output impedance in
the audio signals, so you are doing some kind of uncontrolled mixing with
resistors.
The suggested solution using the line-in (external or internal) input is
more profesional.

  Starting point:        (-1)^(-1) = -1
  Applying logarithms: (-1)*ln(-1) = ln(-1)
  Since ln(-1) <> 0, dividing:  -1 = 1     (ln(-1) is complex, but exists)
