Title:
  [USB-Audio - C-Media USB Headphone Set, playback] Playback problem

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I can hear sounds fine, but the left and right are switched.

  It is bothering me because I have headphones that cant be used "the
  wrong way".

  I am using Cambridge audio DAC as usb sound card, and it works fine in
  windows, and good in ubuntu except for the left/right problem.
