how to mute microphone in vista

[almach1]

OK i have vista prem with an x-fi.

how the hell can i mute the microphone. it's always on, so there is continuous hiss and reverb on my speakers. I know in XP how to mute it, but in Vista i cannot find it for nothing!

nevermind it just stopped. i finally found where to change the playback levels. Didn't change anything. when I went to the page, it just stoped playing back mic pickup. i have no idea how this got fixed, but it did. at least i know where to mute it now.
