Mono sound in Mandriva 2007.1 on Realtek ALC850
 

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.

Problem solved
It was sufficient to run alsaconf as root
