I run alsamixer and after probing all controls I found the muting Mic
Boos and Headphone solved the noise. I still can hear the noise too
low but only when I increase the Volume of my speakers to maximum. I
think that this is pretty normal.

Thanks a lot, I really believed that there was a problem with my
Debian Lenny. I didn't think that something so simple such as
adjusting alsamixer would be the solution. I feel ashamed :$
