No one can hear me and I cant hear them

So I can't hear anyone in mumble and they cant hear me. My headphones in windows 7 is picking up their sound though, but just not transmitting it to me, and my mic isn't picking up anything in windows 7. I have tried switching mics but nothing is changing, and nothing in my setting seem to be changed. I already tried uninstalling, and re-installing but that didn't change anything. I have checked my settings countless times to make sure that the audio input and output is set to the right device. If there is anything in my settings that I might be missing please let me know. But I still have no idea what is going on.
