There are some issues (both audio and game freezing) caused by background software for Logitech headsets/speakers ("Logitech Gaming Software"). This doesn't seem directly related to that (Turtle Beach is a different company), but I figured it might be worth mentioning. In any case, thank you very much Hideookino for sharing. If anyone else gets good results from this workaround, please let me know. I'm sending this thread to the team.
