When you double the sample rate it halves the latency for a given size
buffer.  So, you would generally expect to use larger buffers when
running at 96Khz.  With your hardware, I'd expect -p512 to work, if
the system hardware and software are properly tuned.

That is a non-trivial task, however.  Here is a good place to start...


There are also JACK-specific issues to be aware of.  Here is an update
for the JACK FAQ I'm currently working on.  Comments and suggestions
are welcome...
