-Since the cards do have a name, is there a way to ensure that jackd is using the right card ?
-In plain humans terms, that would be tell qjackctl "please, tell jackd to only use this sound card. And if it's not there for some reason, don't fall back on anything, insult me until I plug [MySoundCard] in" can I talk to him like that ? Is that a bit rude ? ;)

Right now pulse audio is yelling away in the logs, and I'm starting to think of an exclusive setup : [PCintelSoundCard] and [pulse] OR [MySoundCard] and [jackd]

pulseaudio[22353]: module.c: Failed to load module "module-alsa-card" (argument: "device_id="2" name="usb-Novation_DMS_XStation-00-XStation" card_name="alsa_card.usb-Novation_DMS_XStation-00-XStation" tsched=no ignore_dB=no card_properties="module-udev-detect.discovered=1""): initialization failed.


Well it sures is confused with names too :)
(I unplugged/plugged things for testing, I'm just saying)

But for that I have to know how to make sure that the worlds won't collide, I really hope that this PCM name thing is reliable...

I mean, it works, it works if I just :


jackd -d alsa -d hw:XStation
jackdmp 1.9.6
(...)
Acquire audio card Audio2
creating alsa driver ... hw:XStation|hw:XStation|1024|2|48000|0|0|nomon|swmeter|-|32bit
(...)


and then


jackd -d alsa -d hw:Intel
jackdmp 1.9.6
(...)
Acquire audio card Audio0
creating alsa driver ... hw:Intel|hw:Intel|1024|2|48000|0|0|nomon|swmeter|-|32bit


-How can I make sure to retain this all along my audio session ? It seems that qjackctl, at some point, translates this name into the corresponding index, puts it in its

InDevice=hw:N
OutDevice=hw:N
vars or in .jackdrc, and then the magic is broken :(

EDIT Using the "Preset Name" feature, it works ; I'm not sure about the soundcard waltz but at least my other settings are retained.
-To what files, or settings, do those labels correspond ?
[Presets]
DefPreset=STUDIO
Preset1=STUDIO
Say I want to export this whole config to another machine, patchbay and everything, how will this "STUDIO" be carried along ?
