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?
