Make sure your soundcard is set to 44.1 not 48 as the sample rate.

If that isn't it, please tell us more about your system, particularly your operating system, soundcard and drivers. Also, please describe how they are out of sync. Is it constant, or shifting? Does everything work correctly in BIAB, just not in RB?
