Razer Kraken V4 Sound

When using discord on my Razer Kraken V4 device, I select the audio output as Razer Kraken V4 - Chat, I select the main sound of the system and the games as Razer Kraken V4 - Game, sometimes the whole sound goes completely, sometimes it goes for 10 15 20 seconds, sometimes it goes and instatntly comes back. I tried everthing like unistalling synapse , unistalling thx drivers , install synapse 3 , synapse 4 . I cant find any solution. I dont know its about software issue or hardware . Its only happening use seperate device , If I choose Razer Kraken V4 on both windows and discord there is no issue.
