Oculus I really hope you solve this problem because my bluetooth headphones aren't working because of this. I tried to remove it without any affect and then if I turn bluetooth off and back on it's there again. Uninstsalling Oculus software solved the problem.
I right clicked on sound in the task bar (bottom right), clicked "Open Sound settings" then "Manage sound devices" then there I found "Headphones: Oculus Link Virtual Audio Device" under "Output Devices > Disabled" as well as "Input Devices > Disabled". After I clicked it and clicked "Enable" I saw it as an option for output device back in the task bar (lower right) and after I selected it, I heard audio in the headset.
The last Oculus software release included a driver update which re-installs and re-enables this virtual driver, stomping all over your audio devices. This driver serves no purpose for Rift users and the installer behaviour is a nuisance.
