I would then
need quite a
lot of RAM to use the "--realtime" option. Is it
really necessary to use _that_ much RAM ?
No. Try running jackd with the --unlock option. This is the best solution. JACK clients should
I can't start jackd with that option even though I can
see it loud and clear in the man page as you say.
jackd --realtime -d alsa
starts up, but
jackd --realtime --unlock -d alsa
or
jackd --realtime -u -d alsa
says "unknown option character" and jackd outputs a
usage message where both "-u" and "--unlock" are shown
as examples. Huh ?! Is my jackd broken ? I installed
it through apt-get on my Debian Sarge. Version says
0.99.0.
I also tried
to renice jackd with -20 so it runs
with
priority 0. Will the "--realtime"
option give me
better stability than the renicing ?
Yes, absolutely. Renicing JACK is the wrong way,
because it's still
subject to dynamic priority adjustment by the
scheduler.
