oculus virtual audio device missing

do this c:\Program Files\Oculus\Support\oculus-drivers\oculus-driver.exe

Within the Last 2 months the oculous software has added a toggle to just turn off speakers and mics. This is much better than what I had to do, which was uninstall drivers and reinstall drivers prior and after every time I used the quest.

If anyone else has mic problems after using quest it is a windows issue. Windows sets the default microphone to quest in both windows settings and game bar. So if you set it back to your real mic in windows not all games will follow this setting. So check game bar if you have mic issues. Halo for example. Has this issue, when in game hit wind+g to enter game bar settings. On the left hand side of the ui there should be a window for audio. Switch the audio to inputs and select your real mic there.
