Directsound Slaving info problem

I am developing an analog capture filter driver. There was an AV sync issue
after the long time live source playback (>2 hr). The audio pin always queue
few buffers after long time playback. I have checked the video and audio PTS
with each media transfer sample, they look like no problem.

I have a question with Default Directsound Device filter. There is
information in Default Directsound Device Properties->Advanced->Slaving
Info->Rate. The “Rate� should be 48KHz with my device, but it will be changed
with the “High Err� and “Low Err� parameters. Could I set any parameter to
change the “High Err� or “Low Err� values in audio pin of analog capture
filter?
