[Launchpad Bug Tracker <1296425@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package ubuntu-drivers-common - 1:0.2.91.9

---------------
ubuntu-drivers-common (1:0.2.91.9) trusty-proposed; urgency=medium

  * sl-modem plugin: Keep environment for aplay, just ensure it's using the C
    locale. This avoids staring pulseaudio twice and causing races for
    attaching devices to pulseaudio. (LP: #1296425)

ubuntu-drivers-common (1:0.2.91.8) trusty-proposed; urgency=medium

  * gpu-manager.c:
    - Refine checks for blacklisted modules, so that we don't end up
      catching false positives (LP: #1376966).
      Thanks to Pär Lindfors for the patch.

Bug description:
  [Impact]

  On the current kubuntu 14.04 live-image (and for a 13.10 upgraded
  system) pulseaudio is running twice. This makes attaching/deattaching
  of usb-headset and other stuff impossible because the two instances
  fight over the events.

  The fix is https://github.com/tseliot/ubuntu-drivers-
  common/commit/5fe70ce1

  [Test Case]

  To reproduce just boot up the current image and do a "ps -ef | grep
  pulseaudio"

  [Regression Potential]

  Low. This fix has been out for many months in 14.10, and only changes
  the environment that "aplay -l" gets called with. In the absolutely
  worst case if this goes totally wrong, ubuntu-drivers would stop to
  detect sl-modem capable soft-modems.
