Description Need Real Name 2002-11-01 05:47:10 UTC
Description of Problem:
Sound doesn't work on Intel (original) motherboards with in-built ICH4 audio.
The following error message comes on using modprobe with the i810_audio driver
(which is what is supposed to be used): Primary codec not ready
On using sndconfig, the error is "init_module failed"

Version-Release number of selected component (if applicable):
kernel version 2.4.18-17 (which is the latest update)

How Reproducible:
This happens always and on all systems with the above-mentioned hardware.

Steps to Reproduce:
1. not applicalble

Actual Results:
The module should have got inserted without any errors and sound should have
worked correctly.

Expected Results:
sound doesn't work

Additional Information:
I have fixed this bug by placing a very small hack in the i810_audio.c which is
the kernel sound driver. The hack is ugly but it makes sound work perfectly once
the kernel/modules are recompiled. This also worked perfectly for other people
who had the same hardware and they were able to get audio perfectly !!

I beleive this bug is related to bug 76830 .

Comment 2 Need Real Name 2002-11-08 10:23:19 UTC
The problem can be fixed the following way by adding a small hack to the driver
source code. Go to /usr/src/`uname -a`/drivers/sound/i810_audio.c and add 
"return 1" at the beginning of the function i810_ac97_exists() so that it always
returns 1. Recompile the modules and install them. Sound would work now !!!.

This is definitely a bug in the i810_audio.c file of this kernel version which
needs to be fixed by the maintainer/developer.
