["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Gioele Barabucci, this bug was reported a while ago and there hasn't
been any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

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.
