View Full Version : [all variants] ALSA problem of snd-atiixp

May 11th, 2009, 04:32 PM
I was wondering whether this bug has been fixed in latest version or not.
From same link

Problem Description:
Loading 'snd-atiixp' kernel module gives:
atiixp: codec read timeout (reg 0)
atiixp: codec read timeout (reg 3c)
atiixp: codec read timeout (reg 1c)
AC'97 2 does not respond - RESET
AC'97 2 access is not valid [0xffffffff], removing mixer.
atiixp: no codec available
ACPI: PCI interrupt for device 0000:00:14.5 disabled
'codec read timeout' lines are repeating many times. Due to
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2081 it is ACPI problem.

I get the same problem for my motherboard Foxconn RC4107MA-RS2
From feisty to jaunty I am getting the same problem.
What is this problem. Could anyone explain?

How to fix it......currently I am using OSS drivers which work but workaround are needed to make the system compatible

Is there anyway I can check whether this bug has been fixed in latest kernel.....it is very old bug.
I also foud a new link
Although I have a diffrent motherboard the problem is same.

Now it is time to wait until this will go into mainline.
Has this patch been integrated into the Kernel

Anyways....can anyone provide a link for a HowTo to install this patch

I found out that the patch was for atiixp.c file in alsa driver source and it had been applied, but it was for a diffrent motherboard.

Finally found out how to make ALSA drivers work for Foxconn RC4107MA-RS2
Add this line to the file /etc/modprobe.d/alsa-base.conf

options snd-atiixp ac97_codec=0

This make the driver take the ac97_codec directly instead of probing it because probing it results in codec timeout error
