Loving my Razr Maxx HD, however my microphone is not working for any app like Shazam or Google Voice Search. It works fine for phone calls, and the applications work fine if I plug in my headphones that have an attached mic to them. Otherwise, without the headphones Google Now says: "Didn't catch that. Try speaking again" and Shazam says: "Couldn't tag, another application might be using the microphone". I am on Jelly Bean and the phone is not rooted, if that helps. Is there a fix for this?
