Players who specifically encounter difficulties with voice communication through the Oculus headsets should check to make sure that the USB connection is through a high connector (3.0) instead of a 2.0 port. If your voice chat is diminished after verifying the high connector port type, we recommend switching the connection through another available USB port on your system.
Please also make sure that your Oculus drivers are up to date.
