Hello Seth, do you have a way to reproduce this state? I. e. by
upgrading packages, or switching between users, or similar? I haven't
hard (or heard of) similar problems recently, so I don't have an idea
yet in which situations this could happen. Thanks!

** Summary changed:

- Audio doesn't work 
+ no dynamic ACLs on /dev/snd/*

** Changed in: systemd (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  no dynamic ACLs on /dev/snd/*

Status in “systemd” package in Ubuntu:
  Incomplete

Bug description:
  My 14.04 LTS laptop no longer plays audio, where earlier releases
  played audio fine.

  A strace on alsamixer shows several failures:
  open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = -1 EACCES (Permission denied)
  open("/dev/aloadC0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

  It appears the permissions on /dev/snd/controlC0 weren't properly updated after I logged in:
  $ getfacl /dev/snd/controlC0
  getfacl: Removing leading '/' from absolute path names
  # file: dev/snd/controlC0
  # owner: root
  # group: audio
  user::rw-
  user:lightdm:rw-
  group::rw-
  mask::rw-
  other::---

  Thanks
