first call to alSourcePlay problem

So i'm running into this weird problem with OpenAL on Windows. The first
time i call alSourcePlay, the audio sounds a little different. Subsequent
calls to the same source work fine. I suppose it could be related to popping
or clicking, but it's more subtle.

I'm currently using stb_vorbis to decode an ogg file, but i've tried this
with wav files and ALUT. I've also tried different sound files. Same thing.

I did try the alutHelloWorldBuffer function, and that seems to play fine. I
wonder if different sample rates / settings affect this problem differently.

This problem does not occur under Ubuntu 9.10. I've tried Windows 7 and XP
with the same results. I'm using the latest SDK / bins.

I created a test project if anyone else wants to give it a go:
http://www.cs.utah.edu/~witkowsk/files/audtest.zip

If you go into the working directory and run audtest.exe, 3 sounds will
play. The first one sounds kind of like a plastic bat, the next 2 play just
fine.

Anyone else run into this?

Thanks
