R0STUB.SYS

Is somewhere used by MMOS2. R0STUB is the ring-0 half of the sync-stream-manager (SSM) that allows MMPM/2 to synchronize audio and video. Allows audiosh.dll to talk to audio drivers vis IDC entrypoint. In the beginning, all the streaming took place at ring-0. Later (Warp 3?), the audio streaming was moved to ring-3. The API still had to be maintained to audio driver. R0STUB is small piece of code that takes FIFOs buffers to/from MMPM/2 ring-3 audio stream handler and delivers them from/to the hardware vender audio device driver.
