[SOLVED] Razer Tiamat 7.1 V2 not working

[SaltyPickle]

I had those mentioned headphones for over a year and they worked fine until today. I turned on my PC and the light on a doc (MIC mute button and 7.1 button) flashed 4 times and then turned off. I have ASUS Prime X470-PRO motherboard and using sound card for tiamat, Asus Strix Raid PRO. Already tried to unplug everything and tried to switch USB ports bit nothing works. Help!
