It's a Linux problem at the start; I have no idea where the 48KHz
default for so many Linux installs came from. The slightly higher
frequency range isn't worth the conversion if you'd have to burn a CD.

Anyway, I think this is what we need;
http://jackaudio.org/files/docs/html/group__ServerControl.html#ga62022d4f2fbfba065f0874a497afd3b4

A jack client can poll the server for its sample-rate. For Jack-ChucK
that call should perhaps take the place of the default that the s-rate
is set to when -sr[n] is not set at starting the VM.

That way, if somebody does find a use for a mis-set -sr (s)he can and
in other cases it should Just Work.

Now we just need to hope that call is available in the same form for
all editions of Jack ;-) If not I would lean towards requiring Jackd2,
which is far more generous in what it accepts from clients, good for
clients prone to experimentation.

I did some development on connecting to Jack, but not too much and
will defer to a actual expert if we have one.

Yours,
Kas.
