It's probably OpenAL-Soft misusing ALSA, or a buggy driver, or both.  
We just went through a lot of pain with SDL to get this to work well,  
and found a lot of longstanding, non-obvious bugs in our code...but  
also found some drivers for perfectly reasonable audio hardware just  
simply don't work well.

The OpenAL shipping with Aquaria is a recent snapshot of OpenAL-Soft's  
Subversion repository...I'll have to dig into it. It might sense to  
just have OpenAL talk directly to that SDL code we just spent all that  
time debugging.
