Problems with Controller

I have recently purchased an xbox one controller, the first couple of days it has been working fine, however today when using the controller everything was normal then it stopped working. The light of the xbox button was on however it was not connected to
the xbox. I have tried updating, resyncing the controller and I have also reset my xbox however the problem is still there.

Problems with controller/mic

Seems im having problems with either the controller or mic. Not sure if the problem is a hardware problem or a problem with Activision, as im playing zombies on BO3. !st off, during lobby/game searches in Zoms i meet many people with mics, but very few speak
when spoken to, which tells me there is a chat problem somewhere. Many times some people can hear certain players, but not others and vice versa. I purchased 3 new Xone consoles, and after hooking up mine and my sons we were having problems hearing each other
right from the start, sometimes i can hear him but he cant hear me etc. Someone told us to make sure to have our mics plugged into the controller before starting the system, so the mic would "Link" to the controller. Well, this sounds off, because what if
during a game my battery gets weak, and i need to change controllers with a fresh battery, its not like i can switch controllers, and cut the machine off to link mic to new controller during a game. I also noticed that when i wanted to switch controllers
during a online session, it said for me to "Link" the new controller to system, when i had already linked it before. If i have 2 new controllers, both linked to my Xone, shouldnt i be able to merely cut off the one im using, and cut on the other one during
gameplay without re-linking them? As this is the whole reason for having multiple controllers with fresh batteries... I suppose my next is to play another game, such as Halo to see how our mics/chat are working with that game, as it could be a problem with
Activiral and BO3.

 

Problems with a controller....

Like what, compressed air? I've tried blowing in the jack but would air work? Any suggestions?
