I am running XPlane 11.26 in VR Mode (Oculus Rift). I am running Windows 10 Professional (latest updates). For some reason I no longer have any sound (engine noise, etc.) when flying XPlane. I have deleted/renamed the Preferences file in the output folder but that has not made any difference. I ran the XPlane 11 Update process and it stated that I am on the latest version of XPlane. I verified, in settings, that all of the sound sliders are all the way to the right and that "Enable Sounds" is checked. How can I get sound back in Xplane?
