Audio issue after updating Opensuse from 12.3 to 13.1

Hello

It seems that updating my Opensuse doesn't bring me any luck!

I have updated my Opensuse, passing from 12.3 to 13.1. The process went smoothly and no error message was seen during the process. But when I rebooted I noticed that something wasn't right. The first unusual thing was the booting menu:

Code:

# Modified by YaST2. Last modification on Sun Apr 20 21:10:17 BST 2014
# THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader
# For the new kernel it try to figure out old parameters. In case we are not able to recognize it (e.g. change of flavor or strange install order ) it it use as fallback installation parameters from /etc/sysconfig/bootloader

default 0
timeout 8
gfxmenu (hd1,1)/boot/message

It never happened to me, because once the system updated everything related with the 12.3 version should be overwritten. On top of that I lost the audio. I checked different times and volume, PCM settings are the same as before. So in a terminal I computed the following command:

amixer > amixer-output.txt

And this is what I got :

And as far as I see it sound good to me. Any idea ?
