I just had the same issue on my HTC One M7. Reflashing ROM solved it !
Make sure "ok Google" detection is on for every screen. Do this by opening the Google app, navigate to settings > voice > "ok Google detection" and make sure the "from any sceen" option is enabled. Hopefully this solves your problem.
Go to https://www.google.com/settings/accounthistory/audio and turn on voice searches and commands.
