Thanks Ken. I doesn't appear to work with any of the line out devices I have - ALO, Turbodock, Slik - yet iPhone dock has a line out. Also, have heard of other items like speakers that use the line out but work ok. Doubt that apple would have changed the pinouts for line out. More likely there is some sort of handshake that happens using other pins that enables lineout, especially since iPhone has built in speaker unlike iPod.
