What I did to fix this was go to the hardware control panel, select Sound Configuration, and enable pulse audio and other options that were not checked. That seemed to fix the issue for me.

hello

Solved the problem by downloading 2010.1 iso and reinstalling .... ,I think the problem was not due to update but due to meddling by me in trying to install from the original mother board dvd  linux driver

Thanks for an excellent OS
