are you sure "S24_3LE" is the proper format for your card?

even if it is a "24-96" card, it may require something like U/S32_??
or FLOAT*_?? format. In principle trying to feed it with an unsupported
format should cause an error, but who knows... 

BTW: what if you remove everything from asound.conf and just play to 
"plughw:0,0" as per default?

If that works, next step is trying to upsample but using the default 
plughw for output, that is something like this (*):

pcm.up96k {
type plug
slave {
  pcm "plughw:0,0"
  rate 96000
  }
}

(*) N.B.: written on the fly. I am by no means an alsa/asoundrc 
expert, so... check the syntax!
