:) It works

Thanks for the idea of testing the sound at startup.

I have boot from the CD and it works so after i have copied all the file of the CD on the boot partition to test if it was a installation script issue. And after the reboot the sound has worked we some errors messages but it works.

so after i have installed again the 3.13 from scratch because i have only update the system from the 3.11. and at this time i have the pcie sound card which dosen't work.

I reboot i test youtube ok and i launch a game, no sound ...
but i had an idea i have closed OWB and it works. I cannot have OWB open with sound and other program. even if i close the page with sound without closing OWB i have issue it works but the sound is noisy.

So the conclusion is when you change the sound card it is better installing again the system.
And close OWB before launching any other sound application.

thanks for the information about the hotfix i will try.

How do you redirect the music unic in unit 0 ?

I am very happy now :)
