I contacted turtle beach support but they just said to turn it off and on then sign out. Anything I can do? 0 Permalink TB Admin December 14, 2017 19:09 @Dan Duffy If you have already contacted the support team, you would need to reply back to your tech rep to continue the troubleshooting process; they would be the best people to speak to about this. 0 Permalink Please sign in to leave a comment.
