[SOLVED] "jack_control" comand analog to "jackd" (jack vs jackdbus)

Hello,

let me say first that I migrated this thread from LinuxMusicians, where unfortunately noone responded
to my thread.

I have been sucesfully starting JACK using "jackd" with theese configurations (different outputs):

jackd -R -dalsa -dhw:USB -p256
jackd -R -p256 -dalsa -P hw:0,0 -C hw:USB

But now I bought a Guitar Pro 6 which needs pulseaudio and I had to install it. Then I found out
that pulseaudio can't work together with jack unless i swap package "jack2" with "jack2dbus".

The later doesn't use "jackd" to start the server but instead uses "jack_control". So when I
try to modify the comands above I get an error that my parameters are unknown.

[ziga@ziga-pc workspace]$ jack_control -R -dalsa -dhw:USB -p256
Unknown command '-R'
Unknown command '-dalsa'
Unknown command '-dhw:USB'
Unknown command '-p256'

Well I was very optimistic issuing the command above. Please can anyone tell me, how to
edit command "jack_control" to start jack server in the same configuration as with "jackd"
command.

Thank you.

I haven't used jack_control, but here's some usage info, might help:
Arch Wiki
jackaudio.org

As for linuxmusicians: maybe you get replies in a more fitting subforum, like "System Tuning and Configuration"? I would have posted there for jack issues.

jackaudio.org

This is same as using command "jack_control" on its own... they realy need to deliver some examples or something.

Re: [SOLVED] "jack_control" comand analog to "jackd" (jack vs jackdbus)

jack_control is unfortunately rather badly documented. runnin 'jack_control' without any arguments seems to be the only 'manual' there is

There's a good example in arch wiki on how to start jack using it.

This should be equivalent to the latter command in your post:

jack_control start.
jack_control eps realtime true # equivalent to -R
jack_control ds alsa # -dalsa
jack_control dps device hw:USB # -dhw:USB
jack_control dps period 265 # -p256

btw, both jack2 and jack2dbus should work with jackdbus (last time I checked), only difference being that jack2dbus doesn't include the legacy jackd command.

Thank you very much. It looks like I should write a scrirpt to execute all these comands.

That's the simplest way I guess. I'm using a script that starts and configures jackdbus and launches renoise (which is pretty only application where I need jack).
I learned recently that you can use qjackctl with jackdbus as well, if you enable Setup->Misc->Enable D-Bus interface.

AFAIK, the jack2 package contains both jackd and jack_control/jackdbus , but the jack2dbus package contains only the dbus enabled programs.

See http://trac.jackaudio.org/wiki/JackDbusPackaging

EDIT: You can use QJackCtl with Dbus support enabled on the Misc tab in the settings. I think you also have to replace all calls to jackd with jackdbus as well.
