The problem here is that the azalia driver does not support mmap()ing
of the buffer, which jack relies on for low-latency audio.  Well, at
least it MAY be the problem; it depends upon your jack configuration
and version.  I have a wip/jack-devel snapshot that you can try
building (let me know if you have any problems with it)--it's version
0.102.28 (the same version in FreeBSD ports).  Do note that jack is a
bad application to test audio with; I'd recommend trying something
which supports sun audio first, like the audio tools included with
NetBSD (I think mpg123 might support it also, but I forget).

I've been trying to find out why the driver doesn't support it, but no
one returns my emails. :(

Best of luck,

"The frivolity and boredom which unsettle the established order, the
vague foreboding of something unknown, these are the heralds of
approaching change.  The gradual crumbling that left unaltered the
face of the whole is cut short by a sunburst which, in one flash,
illuminates the features of the new world."  --G.W.F. Hegel,
