ADSP-21489 switch noise

I'm working on the ADSP-21489 evaluation board. I have got a problem about the switch noise. There are two kinds of switch module, one has clickless SW slew function, another doesn't. Both the two switch modules with "N inputs 2 outputs" will cause a popping noise when the channel is switched. Did I make any mistakes? How can I solve this problem?

Thanks very much!
