[linux-audio-user] ALSA, jack and the other stuff: Two cards handling

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?

> Everything seems to work fine,

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 :)
