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-4.4.0-2/4.4.0-2.16 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. -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 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: -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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1534647 Title: Collateral damage due to kernel configuration change enabling CONFIG_ZONE_DEVICE (Kernel 4.4 amd64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1534647/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
