i used jack with my Echo Gina24 (which has 2 ins, 8 outs) since today,
withous problems.
just today i bought an ADAT I/O box (Fostex VC-8).
in the Echo Mixer i can see, hear and control both analog and digital
channels.
but when i start jack, i only see two analog inputs, and eight analog
outputs.
where did my new digital channels go?
if i force jack to use 10 input channels and 16 output channels (VC-8
has 8 ins and 8 outs), jack says:
loading driver ..
apparent rate = 44100
creating alsa driver ...
hw:1|hw:1|256|2|44100|10|16|hwmon|hwmeter|soft-mode|32bit
control device hw:1
configuring for 44100Hz, period = 256 frames, buffer = 2 periods
ALSA: cannot set channel count to 10 for capture
ALSA: cannot configure capture channel
cannot load driver module alsa
note: i have to set Gina24 to receive external clock from the ADAT box
(its clock is 44.1k) in order to hear/capture the 8+8 digital channels.
why jack doesn't see the new inputs?
thanks in advance

Yours souncard digital in/output may me accessible with your h:1.1
if you want to use both 1,0 and 1,1 with jack you have to merge them
using your .asound or asoundrc file.

i cannot find an explanation on how to do this in the alsa manual.
can you help me? i am experimenting with /etc/asound.conf (i deleted all
~/.asound*) but still not getting to work this.

I haven't checked up on alsa developement lately, so alsa devs may
have found a hack to get around this limitation, but I don't think you
can use these two subdevices at the same time. In otherwards I don't
think you'll be able to set up an asoundrc file to combine the
subdevices in one virtual device. The reason for this is that both
subdevices use the same controller. The controller can only controll
one subdevice at a time, so there is no way you can use both.

hmmmmm.... i am an ignorant.
i didn't know that digital interface is hw:1,1 and not hw:1,0... (just
discovered it in /proc/asound!)
i guess jack doesn't handle multiple soundcards... can work if i start
two instances of jack?

You set up the multiple devices in alsa to present them as one device
to jack. If these devices are not able to use the same clock, they
will drift.
can work if i start two instances of jack?
It is possible to run a jack server on each card and then communicate
between the servers. I cannot point you any place, but I'm sure
someone else will.

my soundcard is able to sync clock via its internal clock, via ADAT
source (optical), or via word clock.
in order to hear ADAT input i have to sync to ADAT clock, and set the
clock switch to "Internal (44.1k)" on my ADAT.
however, if you look at the thread ".asoundrc - merging two soundcards"
you see that i managed to get a such setup with jack, but it is highly
instable, or has something wrong, because it crashes jack after few
second that it is started.
