Unless you specifically create the context with AL_SYNC, there will be a 
thread spawned to handle the mixing.  I use OpenAL all the time under 
Linux and don't have this problem.

Are you using buffer queues, or just a single buffer?  If you're 
queueing buffers, it's up to your application to make sure the source 
always has at least one buffer queued to keep the sound from skipping.
