Voice chat not working xbox

My wife and I started playing last night. I had one game where I could hear my squad mates and since then nothing. Have changed no settings either in Xbox chat settings or game settings. I use the standard Microsoft stereo headset that plugs into the audio jack of the controller. So far every other game has no issues, I can see the opponents mic icon go on and off so it is not a constant lit up, so it shows they are speaking and not in party chat, but still nothing.
