Issue with sound

[Alvenor]

I start the game and sound works perfectly. After a few moments the sound stops working completely in game but sound that comes from outside the game works normally (like notifications or chat sounds). Only way for the sound to come back is to restart the game, and then after a few minutes the same thing all over again. Does anyone else have this issue? Or does anyone know how to fix it?
