You can try the steps below. Also try look here:

Determine your sound card:

~ $cat /proc/asound/cards
  0 [UA25EX         ]: USB-Audio - UA-25EX
                       EDIROL UA-25EX at usb-0000:00:1d.0-1.2, full speed
  1 [PCH            ]: HDA-Intel - HDA Intel PCH
                       HDA Intel PCH at 0xdf600000 irq 22
  2 [mini           ]: USB-Audio - MPK mini
                       AKAI PROFESSIONAL,LP MPK mini at 
usb-0000:03:00.0-1, full speed

In the setup of qjackctl in interface instead of hw:0 hw:1 etc use the 
value in brackets above. In my case hw:UA25EX

yum install alsa-plugins-jack and create the following file ~/.asoundrc.
Set card 0 to whatever number your card has been given above.


~ $cat .asoundrc
ctl.!default {
         type hw
         card 0

}

pcm.!default {
         type plug
         slave { pcm "jack" }

}

pcm.jack {
         type jack
         playback_ports {
                 0 system:playback_1
                 1 system:playback_2
         }
         capture_ports {
                 0 system:capture_1
                 1 system:capture_2
         }

}
