Play sound away after a short time?

If I play a game such as Fortnite or Minecraft, the sound of the game just goes away. I also have the same problem with Discord, the sound is just gone. I can't say anything or you can't hear me and I do not hear the other person. With Discord I must then simply go into the user settings and voice recording device and output device select then it goes again. In the games, this solution does not work.

Looking forward to helpful answers.

Check if all the drivers for your device are up to date! Otherwise, maybe once out and put in.

Hi, thanks for your answer. How can I find out if a driver is outdated?
