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 :)
