Someone who understands the ice1712 driver can probably explain it.
I don't know for sure, but I think maybe the chip forces all 22 I/O
buffers to be mapped into the DMA address space.

That did it! I set both values to 0 in qjackctl and it just leaves them
off the command line. That seems odd that I'd have access to the device
for the I/O of data, but not access to settings like number of ports.
Any insight as to why that is? Either way, thank you very much for your
help! The error seems to point to the channel count,
but whether I specify 2
or the proper number, which is 4, it makes no difference. Permissions
and ownership:group in /dev/sound and /dev/snd appear to be fine.
Try leaving off -i and -o completely. Internally, the chip has 10
inputs and 12 outputs, although the card only has 4 and 4. Just allow
JACK to use them all. It shouldn't hurt anything.
