[ubuntu] asoundrc setting for 5.1 sound

Hi, I would like to remap my 5.1 speakers in alsa from the .asoundrc, but I don't know well how it works. I have seen something like this in another old thread, but it doesn't work for me:

Code:

pcm.swap51 {   @args.0 SLAVE
   @args.SLAVE {
               type string
               default "surround51"
   }
   type route
   slave {
         pcm $SLAVE
         chaels 6
   }
   ttable {
     0.0= 1
     1.4= 1
     2.5= 1
     3.2= 1
     4.1= 1
     5.3= 1
   }
}
This is my output for aplay -L:
