Hello,
Just tried 44.1kHz->anykHz and 48->44.1 without any problem, with cvs of
May,04.
(see if necessary my config at the end this mail)
Sorry for giving feedback so late, it took me some time to understand
the reasons of another problem i had during export, which prevented me
doing those tests:
If i do an export with other jack clients running (eg jamin), everything
hangs at the end. If I trust what i read on the jackit-devel archives,
it is related to realtime capability problems. You (Paul) also mention
that it might be corrected in recent versions of jack (API changes...).
It seems not. Maybe i did not understand what I read, or I did something
wrong.
I usually run jack like this :
jackstart -R -P89 -dalsa -dhw:0 -r44100 -p128 -n2
Note that I have this problem even if i run jackd normally (no RT).
jackd -dalsa -dhw:0 -r44100 -p128 -n2
What is the actual state of the art regarding this complex thing?
