Hello,

When compiled and run with jack v0.99.50, i get the following error with fl.csd:

 *** openJackStream(): error setting JACK buffer size
Failed to initialise real time audio input
inactive allocs returned to freespace


Note that everything works fine with 0.99.22.

Are you running Csound with the same setting for -b that you
use as JACK period size ? I mean something like this:

   jackd -d alsa -p 128 ...
   csound -b 128 ...

Also, make sure that both -b and -B are power of two, and -B
is higher than -b.

Ok, thank you. Everything works fine now. I should have found it myself, sorry.
The problem is that my version 0.99.22 of jack allowed a program to change
buffer size of jack when running. So i did not need to care about buffer size
with csound.

It *seems* that v0.99.50 doesn't allow anymore to change buffer size, the reason
of the error. I don't know if the developpers have disabled the feature or if it
is now a compile time, i will check.

Thanks for the response, so it was not a bug, Csound5 is bug free! ;)
