Comment 15 for bug 1534647

Thank you for confirming this issue still exists, despite "fix committed,"
and that it also disables correct functioning of package 'mudita24'.

Characterizing #12 further (via
" for i in linux-image*.deb; do dpkg --contents $i | grep snd-ice1712.ko ; done "),
I notice the presence of the ice1712 module in rc7
  /lib/modules/4.4.0-040400rc7-generic/kernel/sound/pci/ice1712/snd-ice1712.ko
by rc8, it has gone missing. It continues missing in the 4.4.0 release and 4.4.1 as well.

snd-ice1712.ko is *not* present in the 4.4.0 or 4.4.1 lowlatency kernels as discussed in #5, #6, #7. Therefore no "ICEnsemble ICE1712 (Envy24)" cards will work, even, with low-latency kernel.

The file is present in wily 4.3.0 and 4.3.5 kernels:
 /lib/modules/4.3.0-040300-generic/kernel/sound/pci/ice1712/snd-ice1712.ko
 /lib/modules/4.3.5-040305-generic/kernel/sound/pci/ice1712/snd-ice1712.ko

And though absent in 4.5.0 RC1, the file reappears in the latest RC4
 /lib/modules/4.5.0-040500rc4-generic/kernel/sound/pci/ice1712/snd-ice1712.ko

Question: When/where will a 4.4 release become available with at least some collateral damage, such as the "ICEnsemble ICE1712 (Envy24)" listed in the bug description, working again? Many of the other listed PCI cards are no-longer used or needed. However, the "Envy24" cards are still used by those doing music or media production in Linux because they have unique features -- in particular, extremely low-latency, and a built-in 20-channel 36-bit wide hardware digital audio mixer: http://www.viatech.com/en/silicon/legacy/audio/envy24/
