Before starting the installation, you must put the firmware-iwlwifi and the firmware-realtek packages on the root of a USB key who are here
The installation runs smoothly until the network configuration. It was at this time that the firmwares
installed on the USB key will be requested. After that, all is well until the end of the installation.
The kernel in jessie is: linux-image-3.16.0-4-amd64. With this kernel no sound. I installed the kernel:
linux-image-4.3.0-0.bpo.1-amd64, but with this kernel X11 failed :(
The issue is caused by the package xserver-xorg-video-intel of jessie; installing the package xserver-xorg-video-intel of jessie-backports solved the problem.
For that, you must add in your /etc/apt/sources.list file the lines:

deb jessie-backports main non-free contrib
deb-src jessie-backports main non-free contrib

in replace fr by your country, and do as root in a terminal:

apt-get update
apt-get install linux-image-4.3.0-0.bpo.1-amd64
apt-get -t jessie-backports install xserver-xorg-video-intel

Now wifi is almost ok and the sound is ok.
finally I installed the firmware-iwlwifi and the firmware-realtek of stretch (in jessie).
The problem with wireless is that the connection is interrupted about every 5 minutes.
To solve this problem with jessie I have done: iwconfig wlan0 power off
To see how to run this command at startup visit this link : run a program at startup  (in French)
