I did get jackd to start with a 48 sample buffer size (I thought I had
tried that before and it dropped to 32).  I set the number of periods to
32 or 64, but neither of those settings worked, Ardour connected to jackd
without complaining, but when I played a project jackd had this repeating
on the console:

JackEngine::XRun: client = ardour was not finished, state = Triggered
JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = ardour was not finished, state = Running
JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = ardour was not finished, state = Running
JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = ardour was not finished, state = Running
JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = ardour was not finished, state = Running

No better results trying to use the Ardour ALSA backend, but that only
allows choosing 32 or 64 for period size, it will not allow configuring
for 48.
