Sound problem in Mandriva 2007.1 on Realtek ALC850

[Guest !Xi!]

Hello

I have a problem with my installtion of Mandriva 2007.1.

All of a sudden one speaker went deaf. I thought it is a speakers/headphones problem but it is not. The sound is working properly in Windows.

It is not a kmixer issue. The slider is exactly in the middle of the balance gauge.

Can anybody provide help with this case?

Big thanks in advance.

What happened at "all of a sudden". Did you do some updates to the system? Or was it a case of just using the system, then it just stopped working?

[Guest !Xi!]

I dare to say I found it this way after returining home from work. The sound was fine the day before.

No updates, even no system restart. This states remains after rebooting the box.

This really puzzles me.

Can you post the results from an:

 

lspci

 

on the system, as well as a:

 

dmesg | grep -i alc

 

to see if there is anything relating to the sound codec causing the problem. And then, give me the output from:

 

rpm -qa | grep -i alsa

 

to see what alsa packages you are using. And then give me:

 

cat /etc/modprobe.conf

 

so we can see what alsa config settings are in here. Will help me see if I can check out what is going on.

Ok, here we go

and big thank you for your support

OK, what I suggest doing is running alsaconf to reconfigure your soundcard, so:

 

su (enter root password when prompted)
alsaconf

 

follow the stuff on-screen. It might mute your sound after, so check kmix if you're using KDE to unmute, and then see if sound is OK.

Worked like a charm. Back in stereo!

Big thanks for the help!!

Hi

 

Same sound chip but that solution do not work.

 

At about the same time as th eoriginal poster, also I one day found my desktop sound was gone...

I did not care much then, but now after a fresh install of 2008.1 PWP I still have no sound :(

Alsaconf do not help.

 

Main board: MSI K8N Master2-FAR

Chipset: nForce4 Pro

Onboard Audio: Realtek ALC850

 

In my thread http://forum.mandriva.com/viewtopic.php?t=85787 there have only been answers sharing the same problem, no solution.

 

Maybe someone here have ideas?
