getting mic to work

[haxthegibson]

i have a shoutcast server running, people can connect and get music, but it does not seem that anyone can hear my mic, and when they can hear my mic, its mic only and no music. can anyone take me step-by-step thru the process of setting up a mic input (when i push "push to talk" it will mix in with the current audio) with a soundblaster live card or show me to a site that can? thanks
