You should not need any config files. I don't use them. There is one
file which is created by the system called /etc/asound.state which
sometimes is outdated by Alsa updates. If that happens you'll get
messages when Alsa starts (probably boot time for you - what distro?)
and the messages will say things like a 'control' has incorrect
values, etc. If that happens just erase asound.state and let the
system create a new one.
Will look in and see if I can help.

Well, here's what I've tried so far tonight:
Ran jack as root.
Ran qjackctl as root.
--------------
On the setup/Settings page:
Checked: Realime/hw monitor/hw meter.
Left other messages alone.
Priority: 0
Prames/period: 1024 (a guess)
sample rate:22050 (default...)
Periods/Buffer: 2
Port Max: 128
Timeout: 500ms
Interface: hw:1
Dither: none
Audio:duplex
Input device:(default)
output device:(default)
input channels: 0
output channels: 0
input latency: 0
output latency: 0
Latency: 92.9 msec
-----------
The "input channels: 0" and "output channels: 0"
seem suspicious. If I try to change them Jack
won't start and says: "ALSA: cannot set channel
count to 1 for capture" If I leave them zero, jack
will start (but I don't know if that's right.)
On the AW4416:
On the Setup/Patch In page, it looks like
SL2-1 through SL2-8 are mapped to mixer input channels
17-24. For the mixer 1-24/rtn-1-2, I pushed the faders
up. On the "Home" screen, 1-24/rtn, I can monitor the
inputs.
I ran ecasound like so:
ecasound -c -b:1024 -i:planet-zoing-zoing-banjomix.wav -o:jack
Then "start"
Then in qjackctl, I can see ecasound in the "capture" column,
and I routed it to every single output (all 18 of them --
presumably 2 s/pdif outs + 16 ADAT outs.) So I am seeing
the hammerfall having 18 ports, which is encouraging
I got nothing on the AW4416 where I would expect the sound
from the wav file to show up on all 8 ADAT inputs.
That's where things stand right now.

To set the card's clock rate will likely
require use of some amixer
commands. man amixer and then play around with reading out the
controls in the driver. The correct solution here is to configure
either your Hammerfall or the AW4416 as a clock slave. I don't have
any problems using the ADAT lines to sync clocks so you could try that
to begin with. It will certainly work well enough to test the
connection. You can go to a spdif or Word Clock sync later if you need
it. I'm not sure if you can do Word Clock sync on a DIGI9636 anyway.
That connection may be on the DIGI9652 expander card. I cannot
remember.
Ok, this gives me some hints to play around with, and encouragement.
Thanks a bunch! I imagine when I run, say qjackconnect,
I should expect to see a bunch of inputs and outputs to
the hammerfall? But maybe my config files (asound... ) have
to be correct first? Anyway, it will work. Possibly you can post
back your currect
settings from /proc/asound/cards and the output of amixer's listing of
controls and er can get you lined up pretty quickly.
Ok, I will do that tonight.
