When you 'cat /dev/sndstat', what does it think the sampling rate is
and does that match what you set?  For that matter, what program
did you use to play the sound and did it try to set the proper
sampling rate?

If the /dev/sndstat has the proper sampling rate, check to make sure
the 'outl' macro is doing the proper byte swapping when setting the
control registers on the src_write() function.
