Title:
  Audio codec draining power when not in use

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  in 12.04 no draining power when not in use, but also displays in powertop 100% usege.
  in 12.10 this is bug works, also as down (but usage ~4W always)
  (This problem is not ubuntu, but the kernel in general. I learned forums and there is this problem a lot of people (including gentoo Andes archlinux). Most of those who have HDA Intel, I suspect that you need to complain to them.)

  With no sound playing, powertop reports "Audio codec hwC0D0: Conexant"
  and "Audio codec hwC0D1: Conexant" drawing 1.64W of power each and
  being used 100% of time both. All powertop suggestions have been
  followed.
