Dealing with ADG1604 Crosstalk

My design uses ADG1604 to switch between four audio inputs, then the result goes to another ADG1604 in the opposite direction to select from four audio outputs. The issue I am facing is that when there is an input on channel 1, say an iPod, that is actively playing music, but nothing connected on channel 2, and channel 2 is selected, I can hear a faint version of channel 1 input.

 

All the grounds of the inputs and outputs are connected to the overall system ground. Is there any method to reduce this crosstalk?
