OpenAl & sync points

I was using Fmod to control my sound engine...however, i had to change...now I''m using OpenAl, but I have a problem. In Fmod, there was a way to control sync points and callbacks that were called when a sample reached a sync point. However, in OpenAl, I didn''t find a way to control callbacks with sync points... Is there a way to do this?? thanks ...
