Nexus 7 (2013) 4.4 killed Mic

Sooo I just got my update to 4.4 yesterday OTA. I sideloaded the original 4.4 earlier on my Nexus 7 and ever since I have updated my Nexus 7 my Mic hasn't worked. I was hoping that the OTA would fix this and that this would have just been a bug with the original 4.4. But the OTA didn't fix it. So now whenever I try to use Google Now mic function or even the keyboard mic it never picks up any sound. So I'm basically wondering if anyone else is having this issue? Or does anyone know a fix for this? I am pretty sure I'm going to have to use my warranty, since I haven't seen this issue anywhere else.

But if anyone could help that would be great!
