[Solved] Call of Duty Modern Warfare / Warzone sound from two different devices on PC

The newest iteration to the Call of Duty series, Modern Warfare / Warzone, has a new sound output system where the game sounds are sent to one audio device, while the voice chat audio goes to another sound device.

Changing the default audio device either in-game or from the Blizzard launcher will not fix the problem. Rather, to output both the in-game sound, as well as the voice chat sound, you need to follow these steps:

  • Go to Control Panel
  • Open ‘sound devices’
  • Select the device to which you want to output sound and set it as default.

That’s it. Now open the game. You will notice that both the ingame audio and the chat sound should go to the same audio device.
