Yes, the v4.0-rc3 kernel.  That will tell us if this is already fixed in
the Mainline kernel.  If it is, we can identify the fix and cherry-pick
or backport it in to prior stable releases.

Title:
  USB Soundbar 413c:a503 not working

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Dell ACS11 USB Soundbar with USB ID 413C:A503 works fine in linux
  kernel 3.13-0-45-generic and earlier kernel releases.

  In 3.13.0-46 dmsg shows messages when the soundbar is pluged in and
  unpluged. However it is not listed by alsa or pulseaudio.

  Boot with the 3.13.0-45 kernel restores normal functionality.

  
  1) Release: Ubuntu 14.04.2 LTS
  2) Version:  3.13.0-46.77
  3) I expect to see the Dell ACS11 USB SounBbar listed as an audiodevice in pavucontrol
  4) The SoundBar does not show up in pavucontrol
