In the meantime, please be sure that you also try checking the audio output settings to see if it makes any difference. You may also want to check the settings in-game regarding volume. If neither of this help, please be sure to notify Support with your msinfo and dxdiag so this can be investigated. Please attach the files via "my questions" here: https://support.ubi.com.
