Any buffer size above 0 can be used, as long as it's a multiple of the 
format's block size. You just need to make sure to have enough buffers so that 
they don't all run out before they can be updated, and the amount that is 
depends on the buffers' frequency, how fast your app updates, and the 
device/implementation.

I've haven't been very successful at finding a good buffering/queueing method 
to handle low-latency/real-time audio on top of openal (ie. when you need to 
play what you just got right now). The more you queue, the more you have to 
wait before new samples will be heard, and the less you queue, the bigger the 
chance for underruns.
