Comment 12 for bug 1534647

I've been impacted by this bug, in that it disables all "Envy24" soundcards such as the popular (but obsolete) M-Audio "Delta" series PCI audio cards. See http://article.gmane.org/gmane.linux.alsa.user/39428 .

Additional side-effects/impacts of this bug are that the applications used to talk to this series of music-production soundcards no longer work. Specifically "my" https://launchpad.net/ubuntu/+source/mudita24 as well as the older 'envy24control' that it replaces.

The list of cards this bug disables is long: 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.

The problem persists using the above-suggested "fix" packages of "4.4.0-2.16" which I retrieved from
https://launchpad.net/ubuntu/xenial/amd64/linux-image-4.4.0-2-generic/4.4.0-2.16
https://launchpad.net/ubuntu/xenial/amd64/linux-image-extra-4.4.0-2-generic/4.4.0-2.16

https://launchpad.net/ubuntu/xenial/amd64/linux-headers-4.4.0-2-generic/4.4.0-2.16

Likewise, the problem persists using the above-suggested "lowlatency" kernels.

In all cases, for 4.4.1, 4.4.0-2, or their lowlatency variants, there is a missing "snd_ice1712" module in
/lib/modules/4.4.1-040401-generic/kernel/sound/pci/ice1712/ . The directory contains modules for snd_ice1724 which is a completely different soundcard (which nobody uses or has) snd_ice1724 . snd-ice1712.ko is missing.

In kernel 4.3.0 (directory /lib/modules/4.3.0-040300-generic/kernel/sound/pci/ice1712/
) the file is present and all the envy24 cards I have (Terratec DMX6Fire, M-Audio Delta 66, Event EZ8) work fine:
