SGTL5000 connection

We are using a SGTL5000 to play-back audio (using line-out) and capture audio (using mic-input), with an iMX51.


If the LINE_IN signals of the SGTL5000 are not used, what is the recommended connection for them? (leave unconnected, tie to GND, tie to GND via a capacitor or resistor...)


The typical application schematic on the datasheet does not clarify what to do with these pins if not used.


Thanks for your help!
