Bug Description

I have a Medion 95264 Laptop (same as MSI S250) with an SIS 661MX chipset.
Only weak sound from the jack, no sound thrue speakers at all. I have External Amplifier turnt on.
This is a known problem also for other distributions.

The solution should be this:

So upgrading to alsa 1.0.10.

But right now I am using Ububtu 6.06 Beta and it still isn't working.
I thought that Ububtu 6.06 Beta allready used ALSA 1.0.10.

Changing this file:
/proc/asound/card0/codec97#0/ac97#0-0+regs
using this command:
echo 7a 2090 > /proc/asound/card0/codec97#0/ac97#0-0+regs
also doesn't work because the file seems empty in Ububtu 6.06 Beta

In older versions of ubuntu I did not have rights to change that file.

More information in the Forum from other users:

Hope this can be fixed before the final release.

Note: the original reporter indicated the bug was in package 'alsa'; however, that package was not published in Ubuntu.

Thank you for reporting this bug. Does this still occur on an updated Dapper or on edgy beta?

thanks for showing interest in this bug.
It is still a problem in Dapper and Edgy knot3.
I've tried changing all the switches, but that makes no difference. Here
you can find some extra information:

I did try using this command:
echo 7a 2090 > /proc/asound/card0/codec97#0/ac97#0-0+regs
but when I do it without root , I get an acces denied error.
And with sudo su I get:
bash: /proc/asound/card0/codec97#0/ac97#0-0+regs: No such device

I did not try to install a new version of alsa manually.

Hope you can solve this.

Great work!

Is there a binary release were this fix is already present?
I would really like to test this.
This is/was the most important reason for not switching completely to Linux.
