Update problems... No sound, no USB...

Hi there!
Yesterday i used my PC normally: I used it for browse Internet, hear some music and so on. And some updates were installed.
But today, I started my PC and no sound and I cannot mount USB devices either.
Can you help me?
(I don’t know what information can help to solve the problem.)
thank you very much.

Hi
A known issue with the kernel update, roll back to the previous version or use the test one until the new update appears.

See https://lists.opensuse.org/opensuse/2016-10/msg00739.html

Thank you very much, for your answer.

But I beg your pardon… How I roll back to the previous kernel?

Hi
You can boot via advanced options in grub would be the easiest way, else in YaST Software Management search on your kernel name (kernel-default?) and select the versions tab and select the previous version and it should switch back.

Go to yast - Software management and remove the newest one. Use the version tag at bottom right

Thank you very much! I could to roll back to a kernel previous version.
