Rift S sound stop working few minutes after turnion the headset on

Hey gize, 

I have got a Rift S and im using it on my Alienware R2 15 laptop, intel i7, 16gb ram, windows 10 and with Nvidia GTX 1060 6gb on the alienware graphics amplifier. 

The problem is, after a few minutes of gameplay the sound turns off, and it wont turn on unless i restart the whole Rift system. (Yes i have checked if its in the Rift S sound option, i tried headphones, i tried rift s as default sound device, i tried other USB ports, other Displayport ports). I can not find an answer online, can someone help?

OBS: i used to have a Rift CV1 before i purchased the Rift S now, and this problem never ocurred.

Thanks gize
