What OS? Are you using the latest release (1.15.1), or the latest Git head?

There used to be some problems with PulseAudio devices causing a lockup 
when playback was started, but that hasn't been an issue for several 
versions now.

Sounds like something else it trying to hold open the audio device, 
which is preventing OpenAL from opening it, and that somehow FMOD gets 
the device closed.

I'll need to know the backend OpenAL Soft's trying to use. You should be 
able to get that and other useful info by setting the ALSOFT_LOGLEVEL 
environment variable to "3" when running the app, which will make OpenAL 
print some extra info to stderr (you can also use the ALSOFT_LOGFILE env 
var to specify a filename to write the info to instead).
