Problem using the micro

[BlkGhost]

My problem, is that i have installed de shoucast server and the plugin. I connect the Shoutcast source and work fine, but my problem is when i go to the input device and select the souncard input to use the micro, the sound disapear, only for the ppl that is connected to me. But when i put the input back to the default using winamp, the problem disapears. What can it be? I would like to use micro and i can´t.
