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

Dean Willems, 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 kernel 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-v3.12-rc1

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:
  ALC892 not supported in 10.04 default kernel

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: linux-image-2.6.32-21-generic

  The default kernel installed with Ubuntu 10.04 has no full support for
  ALC892 Audio chip, available on for example the ASUS P7H55-M Pro
  motherboard. Instead, it reverts to a generic intel HD Audio chip,
  offering only stereo playback. In alsamixer, only a master, pcm and
  iec slider appear. Support for the ALC892 Intel G45 DEVIBX was added
  in 2.3.33. A mainline kernel from the kernel ppa (i.e. -
  linux-2.6.33-02063303-generic) successfully recognizes the chip and
  offers the full range of sliders in alsamixer, offering the intended
  5.1/7.1 support. My suggestion is to backport the 2.6.33.x kernel
  module for ALC892 to the current 2.6.32 ubuntu kernel to add the
  correct support of this chip.
