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.
