Sound Problem Cirrus Logic

Hello,

since yesterday i had some problems with my soundcard. A few days ago i made a fresh installation of Ubuntu 6.10. All works fine. After an automatic upgrade the sound didn't work possible as mistake of any lib.

I looked in google and many other information but i didn't found any mistake.

I use a IBM Thinkpad T21:

I've checked the Sound Control and nothing is on mute. If i hit the button for the soundmixer on my laptop a windows starts in the show me the actual volume.
I've checked the internal speaker and external speakers - nothing works.

Any idea? and sorry for my broken english.
