For Ubuntu kernels 4.4.X (e.g. for upcoming 16.04 LTS), the above bug and missing snd-ice1712.ko appears to be the problem.
I've added some comments to the above, and also linked the bug to application mudita24(1) that is disabled by lack of snd_ice1712 module in the 4.4 kernel: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1534647/comments/12
The ice1712 .ko file is missing in 4.4.X:
$ ls -l /lib/modules/4.4.1-040401-generic/kernel/sound/pci/ice1712/
total 256
-rw-r--r-- 1 root root 247046 Jan 31 12:48 snd-ice1724.ko
-rw-r--r-- 1 root root 9230 Jan 31 12:48 snd-ice17xx-ak4xxx.ko
In the 4.3.X kernel, snd-ice1712.ko is present and envy24 soundcards work:
$ ls -l /lib/modules/4.3.0-040300-generic/kernel/sound/pci/ice1712/
total 376
-rw-r--r-- 1 root root 120838 Nov 2 07:01 snd-ice1712.ko
-rw-r--r-- 1 root root 246270 Nov 2 07:01 snd-ice1724.ko
-rw-r--r-- 1 root root 9230 Nov 2 07:01 snd-ice17xx-ak4xxx.ko
If this doesn't get fixed, people upgrading to Ubuntu 16.04 LTS will not have use of soundcards such as M-Audio Delta 1010, Delta 1010LT, Delta DiO 2496, Delta 66, Delta 44, Delta 410 and Audiophile 2496. Terratec EWS 88MT, EWS 88D, EWX 24/96, DMX 6Fire, Phase 88. Hoontech Soundtrack DSP 24, Soundtrack DSP 24 Value, Soundtrack DSP 24 Media 7.1. Event Electronics EZ8. Digigram VX442. Lionstracs, Mediastaton. Terrasoniq TS 88. Roland/Edirol DA-2496.
To the "end user", application mudita24(1) will exit inexplicably, printing only a message to stdout they're unlikely to see:

$ mudita24
No ICE1712 cards found
PS: this message brought to you by Skylake, which necessitates a > 4.3 kernel :-)
PPS: anybody have a pointer to a 4.4.1-compiled snd-ice1712.ko they coaxed out of the build by themselves?
