My problema consists in the fact that Ardour doesn't recognize my external Soundblaster!
The program only sees the internal audio of my laptop, but for recording i want to use the soundblaster because it's better.
Ardour isn't interested in your audio hardware in any way. Interactions with your audio hardware are solely the concern of JACK. When you run JACK, you choose which audio hardware you want to use it with. How do you start JACK? From Ardour itself? From a separate JACK control program such as QJackctl or JackPilot? What platform are you on (Linux? OS X?)
Ok paul, thank you for the explanation.
Now, when i start ardour i don't start jack. not manually...isn't it automatic?
do i have to start first jack and then ardour?
and finally...in jack...how can i set my soundblaster as the input and output?
@7Maverick : If it's a USB2 Soundblaster, chances are it won't work in Linux. Most USB2 don't.
The easiest way to deal with JACK is through QJackCtl. There you have a GUI for setting all kinds of stuff relate to audio, like sample rate and which hardware (soundcard) to use.
Start QjackCtl first, set it up to your liking and click the Start button. Then start Ardour.
ok, now with qjackctl i set soundblaster as the input and output hardware.
In fact, now when i speak on the microphone, i see the soundwaves on ardour.
problem is that i don't have output. if i wanna hear what i registered...i hear nothing.
on jack i have the same setting on input and output...HW 1,0, that is the code for soundblaster. jack sees it.
There are two ways to hear what you record: either let the soundcard (if it's capable) do it or have Ardour do it. To use the latter you have to set Options -> Monitoring -> Ardour does monitoring

Ok, now i have this situation.
Soundblaster runs. I say that because, with jack off, i can listen to music from Rhytmbox. So the soundblaster is not the problem.
now, if i turn on jack, the sound quits immediately. rhytmbox continues to run, but without audio. i start ardour, i speak to the microphone and i see the soundwave, but if i try to hear what i recorded, nothing sounds.
i close everithing, shut down jack, and magically i can hear again music.
In jack setup panel, at the voice "input device" i set 1, because 1 is for soundblaster.
at the voice output device, i set also 1.
where am i wrong?
if i set jack on playback only, sound magically appears! rhytmbox is playing with jack!
i'm going crazy
JACK probably hasn't connected the master out to your Soundblaster.
Click the Connections button in QJackCtl and see where the master_outs are connected.
For more help you should go to the IRC channel (click the text "the main channel" on http://www.ardour.org/support) and see if there's anybody there that can be of assistance.
Setting JACK to playback only (I didn't even know you could do that) has noting to do with Rythmbox playing.
It's probably that the first time you started RB before JACK, so RB played its sounds through ALSA or PulseAudio. If you have JACK started before RB it probably defaults to using JACK before any of the others.
