Mute script issues

[js1974]

I have been working on getting a script to work with Intelliremote to mute my line in and not my master volume but it opens the audio control panel properly and it hits the line in tab properly but for the life of me I can't get it to click the mute button to save my life.

Run("C:\Program Files\Realtek\Audio\HDA\RAVCpl64.exe", "");
WinWaitActive("Realtek HD Audio Manager", "", 3);
ControlClick("Realtek HD Audio Manager", "Line In", "1007", "left", 1, 180, 20")
ControlCommand("Realtek HD Audio Manager", "", "Button15", "Check", "")

I also tried to use ControlClick and hit the button and it doesn't work, I can get it to click in a drop down menu with no problem but can not get it to click the button any help would be greatly appreciated.

So no one with any ideas on how to get this to hit a button?
