Using its digital outputs too

I am working on a film project 5.1 and facing a strange issue. On the large surround panner the speaker icons are not working as I want to mute /unmute but nothing happens upon pressing/clicking on these icons. Whereas it is suppossed to be turning grey upon pressing/clicking and mute that speaker output. i am using TC electronics 24d konnect soundcard and windows7 64.
