card 2: S51 [SB Omni Surround 5.1], device 1: USB Audio [USB Audio #1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

seem capture device id device 1 instead of device 0

You need to define your sound card in USB-Audio.conf

seem use full name instead of S51

USB-Audio."S51".pcm.front {
           @args [ CARD ]
          @args.CARD { type string }
           type asym
          playback.pcm {

                          type hw
                          card $CARD
                          device 0

          }
          capture.pcm {

                          type hw
                          card $CARD
                          device 1

        }
