Thresher ultimate for xbox: audio not working

Hey guys,

I have 2 weeks old thresher ultimate xbox-version and it just stopped working on my xbox. I played for 15 minutes and all of a sudden no sound.

It works beautifully on my computer, but when i connect it to my xbox, i can't get any audio whatsoever. When i connect to xbox, it says that headset is in use and i tested it in party chat that does my mic react to any sounds and it does work as it should.

I bought new optic cable just in case that old one was broken, but still nothing. My settings in xbox audio output are just the way these installing manuals say. Usb from audio hub to xbox, optic cable from audio hub to xbox, fully charged headset, paired audio hub and headset, power cycled xbox..

I need help so bad! Has anyone faced something like this before and what else can i do? I have contacted razer support and they dont have any idea..

All tips are helpful. Thank you in advance.
