[Vincent Tarin <tarin.vincent@xxxxxxxx>]

Hello,

I renew my Kernel, please see the version given by the Terminal

cat /proc/version
Linux version 4.6.0-040600rc2-generic (kernel@tangerine) (gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2) ) #201604031130 SMP Sun Apr 3 15:32:46 UTC 2016

I must say that while the installation, many error occured. I decided to
boot from the Grub to that new Kernel.

But unfortunately, still no sound...

Would it be reasonable to downgrade the Kernel which goes with a Ubuntu
version which makes my sound works ?
