To change audio playback settings, players should right click on the speaker icon in their system tray, select playback devices, and then set both the default device and default communications device to choose the hands-free Bluetooth device. To resolve this issue, players can disable in-game voice chat or they can change their audio playback settings to not use the stereo Bluetooth option.
Players must ensure that Destiny 2 has permission to use their microphone within their Stadia or Windows 10 Privacy Settings.
