Why does mumble cause such bad feedback?

It crashed, it is bugged, ...
Hey guys, recently I've been trying to get mumble working properly with my microphone but no matter how I adjust the settings, backround noises such as my keyboard and cars outside cause horrible, high pitched feedback. This has nothing to do with my hardware itself. Using my microphone (modmic) with any other chat program and even just monitoring through windows has zero feedback. I can shout into my microphone and absolutely no peaking or feedback occurs yet Mumble seems to cause it from nothing.
Please, if anyone has any info about this, help me.
