What exactly doesn't work?

How do you know this?

Do you mean the card is physically broken?
Do you get error messages when you try to use it?
Have you used a program such as alsamixer to bring up the volume level, which defaults to all the way off?

What is "everything"?  You just said the first card didn't work right, and the second card had no output.

If I understand ALSA correctly, this is because it is the default device -hw:0.  I think you would need to explicitly tell ALSA to use a different device.  Have you read up on .asoundrc files?  (I haven't (I know I ought to) - but I think it might be the answer).

Why do you say "-d hw:0" if you want it to use hw:1?  Try this:

jackd -d alsa -d hw:1

Good luck :)

LOL, hi !
I see that it is  "irresponsible" to post a msg begins with 'you know iam the guy xy, I had x problem' ... .

Well:
I have had several problems with my ESS-Solo1 soundcard to start various sound apps which 
using jack ... . The second card, the Es1371, IS able to start jack, the esssolo1 quits with some alsa-error msgs. I first thought the esssolo1-problem is a symbol-problem in the alsa-modules, but a recompilation ( a successfull ) did not change something with the "support" of the esssolo1 with jack.
So my Ess-Solo1 cannot be used via jack. My second card, Es1371, can , but it is physically broken. just the output-port, so this little "whole" where I put the speakers in, you understand ? I want to pipe jack-output to my first card, the Ess-Solo1. So I want to use my Es1371 for my MiDI-keyboard, for capturing AND for STARTING various soundapps like muse,ardour and Rosegarden4 and so on, but let the Ess-Solo1 output all the stuff jackd gets. (*puh* )


So, my cards are NOW:
Ess-solo1 	<->	hw:0
Es1371	<-> hw:1

# jackd -d alsa -d hw:1 -P hw:0

Should set jack to USE the hw:1, so Es1371 and output via hw:0, my Ess-Solo1, right ? I think thats the question of my originally mail ;)  . Sry, but I exchanged the order of both cards, I think in my first mail Ess-solo1 was hw:1 , but this is not good. You pointed it: My ess-solo1 is my normal sound-card for listening to music and so on, and it should be the first alsa card.
So, the above command prints out the help-menue which u get via:

# jackd -d alsa --help

Why ?
