Ubuntu does not add users to audio by default as some other distros do, so
it has to be done manually :P Hopefully this will change.
HOWEVER ... I have lost some of my M-Audio cards
functionality.
qjackctl's [Connect] window under the Audio tab

on the right, and then on the left, I see:

BUT NOW, since my problem with starting JACK up,
the "Writable Clients/Input Ports" box is blank.
I lost my eight "writeable ports" and I am presently
working to get them back. Any tips would be
appreciated.
Have you tried to see if your s/pdif in works now? That looks like it
"may" be hw:0,1 jack has been started with.
In qjackctl, setup screen, there is an "Interface:" box in the top(ish)
right corner, beside that there is a ">". If you click on that, there
should be a list of devices. Maybe give us a list of those. (full text)
Incidentally, what do these eight playback connections
represent. The "M-Audio Audiophile 2496" only has
three outputs, left and right analog and S/PDIF.
And so do these playbacks 1 through 8 refer to some
sort of mixing channels in the firmware of the
Audiophile 2497?
The ice1712 has 8 analog outputs and 8 analog inputs as well as s/pdif in
and out (and some other stuff) It does not monitor the outputs to see if a
DAC is connected to them and so they all show up. The card manufacture
chooses how much of this they will use. It seems there is enough
communication from the ADCs that the chip can tell what is connected or
not... or maybe the kernel module is more picky with the 2496 than with
the d66. M-Audio may have added some glue logic that keeps this card from
working just like the other delta series cards. It may be interesting to
see if forcing the kernel module to see this as a delta1010 will give you
full access. (including things that are not there.)
Normally with the ice1712 there should be 12 inputs (8 analog, s/pdif pair
9 and 10 plus the multi-mixer outputs 11 and 12) and 10 outputs (8 analog
and one s/pdif pair) In the case of the 2496, inputs 1,2,9,10 and outputs
1,2,9,10 should be valid. However, it looks like the kernel driver is not
set up that way. Channels 11 and 12 (inputs) should also be available as
the output of the internal mixer and all outputs (10 of them) can be used
as inputs to this intenal monitor mixer. (this sounds nice, but the
reality is I have never used it :) as I have an external mixer already)
try adding a line to /etc/modprob.d/alsa-base.conf (this assumes a debian
based distro... Ubuntu for example)
options snd_ice1712 delta1010
(or delta1010lt)
(from:
https://www.kernel.org/doc/Documentation/sound/alsa/ALSA-Configuration.txt
)
See if jack then shows 12/10 i/o and your s/pdif audio shows up on input 9
or 10.
Oh my card is definitely the "M-Audio Audiophile 2496". It says
so on the box. And the commands aplay and arecord list the device as:
card 0: M2496 [M Audio Audiophile 24/96], device 0: ICE1712 multi [ICE1712 multi]
Subdevices: 1/1
Subdevice #0: subdevice #0
Then the below should not work:
[...]
zita-a2j -d hw:0,1 -r 48000 -p 256 -n2 -c 2
alsa_in -j spdif -d hw:0,1 -r 48000 -p 256 -n 2 -c 2
