I have the same unit (have had for about 10 years I guess). I added
this line to /etc/modprobe.d/blacklist.conf
because that caused all sorts of grief if I left it active. The other
thing I did was 'sudo chmod 644 /usr/bin/pulseaudio' but that's just
because I can't stand pulse ;-) I know, there are all kinds of things I
can do to make pulse and jack work together but I just don't need pulse
(I'm following the KISS principal).
On my system:
00-00: ICE1712 multi : ICE1712 multi : playback 1 : capture 1
00-01: ICE1712 consumer : ICE1712 consumer : playback 1 : capture 1
00-02: ICE1712 consumer (DS) : ICE1712 consumer (DS) : playback 6
Even though it says playback 1 : capture 1 for multi, I show all 10
inputs and 8 outputs (I only use PCM Out 1 and 2) when I run mudita24.
Never try to use the consumer stuff, it doesn't work. You don't need it
