Some more analysis from Padraig.

I tried opening in non-blocking mode and this had the effect that the sound
stopped bei ng emitted, (just?) before the first write call which took about
2.6 seconds.

When we are running the sunaudiosink program does the process have /dev/audio
open the whole time so there is no possibility of some other process attempting
to use the device?

My view, now, is that the writing is happening too quickly rather than too
slowly; the STREAMS buffers being maintained for the audio data fill up and the
write system call blocks until that data is drained.

I need to figure out whether this theory fits the facts we have when the sound
stutters and if so, what we can do about it.
