Thanks for the input.  In the end, I hacked up a version of the
test/latency.c to do what I needed.  I think the root of the issue is
that ALSA behaves badly if both the period and buffer sizes/times are
configured, and the values provided do not match up (in terms of the
buffer size relative to the period size).

Anyway, I've got it working now, so thanks anyway!
