pulse jack and USB sound-card

Hello. I have jack and pulse running. I can use them with my onboard card. How can I tell jack that it is my USB-one that I want to use at a special moment? In pavucontrol it is only the jack-sink that is available. I start jack with "jackd -d alsa"

Re: pulse jack and USB sound-card

Use "aplay -l" to get a list of sound cards on your system.  Use the card number you want with jackd like so: "jackd -D alsa -P hw:number -C hw:number"

For example, my usb interface is "card 1", so I use "jackd -D alsa -P hw:1 -C hw:1"

And for future reference, just use "man jackd" or "man program" for whatever you need to figure out. Manpages are even better than google

exept when man pages belong to the gnu project. then info pages are better than manpages.. sometimes.
