combining two subdevs of the same device

[federico <xaero@inwind.it>]

i just bought an ADAT I/O box (8+8).
i plugged into my soundcard, believing that it would extend my number of 
audio channels, from 2in+8out to 10in+16outs.

unfortunately seems that jack can't handle more than one (sub)device at 
time (i can use hw:1,0, wich is the analog part, OR hw:1,1 wich is the 
digital part)

i tried even various configurations of /etc/asound.conf, trying to merge 
the 1,0 and 1,1 subdevs, but no luck (you can see my asound.conf files 
in te bottom of message).... and someone told me that i cannot merge two 
subdevices that are part of the same device, because the ctl.* is the 
same, and it cannot control both subdevs.

does anyone knows how to workaround this?


here is asound.conf (1st try): (i used asym because Gina24 has 2 analog 
inputs, and 8 analog outputs)

pcm.!default {
   type plug
   slave sl44100
}
ctl.!default {

   playback {
       pcm {
           type null
