Windows 10: Voice chat issue /Need advice/

Like the title says, I keep having issues being in voice chat.. I play call of duty cold war/CS:GO and the microphone and headset works fine , however call of duty warzone, xbox party chat and discord just wont work, they can either hear me and I cant hear them or no one can hear anybody, I have all latest drivers installed I've messed around with the settings but certain apps and games just dont work with voice chat and some do I cant understand it because last month or so everything worked fine with no issues apart from an occasional restart to fix the blackout moments. I'm using a sound blaster kratos speaker set and im plugging in my razer headset through that speaker set using the headphone jack on the sound control dial. Any help would be appreciated.

Hi Samuel,

A factor why you're voice chat sounds goes through your speakers as well is due to configuration settings. We suggest that you configure playback devices. Follow the steps below:

• Go to Control Panel > Hardware and Sound >
  Sound.
• Left-click on Speakers > Click on Set as Default Device.
• Left-click on Headphones > Select Set as Default Communication Device.
• Click OK.

If the issue still occurs, contact your device manufacturer's support for assistance on configuring your device.

Let us know what happens after following the suggested troubleshooting steps.
