My friend's Xbox One has a problem with the Party App. Whenever it is used, everyone in the Party hears a muffled robotic like voice, and that's how he hears us. Believing it to be a problem with his internet, I told him to bring it over to my house, where I can hear everyone clearly. We hooked it up and connected everything, made sure it was working properly, and tested the app. When used, it held the same results, muffled voice. We have tried for awhile to fix it, but we can't find anyone else with this issue. Would it be an internal problem? Please help.
