      Description

      When ReactOS is booted after 2nd stage setup, it starts to enumerate audio devices/streams, but for some reason, the proper entry at

      HKLM\SYSTEM\CurrentControlSet\Enum\SW\{cd171de3-69e5-11d2-b56d-0000f8754380}\{9b365890-165f-11d0-a195-0020afd156e4}
      

      is created after that enumeration which causesĀ this code path to trigger:

      There is no entry in registry -> PnP manager doesn't know which driver to use -> the device is never started.

      After that timeout finishes, the devices are removed and registry entries appear somehow so after next reboot the audio should work (here another related issue breaks in CORE-9986)
