Title:
  ALC892 not supported in 10.04 default kernel

Status in “linux” package in Ubuntu:
  Invalid

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.
