Multi-track recording synchronization issues with Audacity.

I'm trying to record some acoustic demos in my room. I've previously made similar home recordings with Sonar and have had no problems. However, I don't have Sonar on my laptop, so I've been using Audacity (1.3b). I record with a condenser mic into a Presonus TubePre, then into my external Soundblaster Live USB, then into my laptop.
The problem is that nothing I record will be synchronized. If I generate a beat track in Audacity and then record a track of myself clapping along with each click, when I play the track back it begins synchronized and then slowly drifts more and more out of time, as if the length of the clip I just recorded is somehow altered slightly after I record it. The only way around this that I've found is to record only very short clips and then make small adjustments by hand when I need to, but this is obviously far from ideal.
Does anyone know why this is happening? Is it a software or hardware issue? I'm not monitoring what I'm recording and I don't need to, I just want the track to play back at the same tempo I recorded it.
