In the meantime, i managed to solve it. I disabled pulse audio globally, so i can use alsa instead and now it works as expected. 

Thanks for your help.

 See - this howto does not install pulse at all.

Hi fritsch!

Need your help : in my kodi machine the videos are jerky 
I don't know why, I think it's all configured properly!

my htpc is this : ZBOX CI323 nano , It is connected to my synto (only at 1080p) and by synto goes to tv (it is a 4K Samunsg)
know that I can't see videos in 4 k but at least I would like to see movies in 1080 p so perfect

I installed ubuntu 17.10 minimal and do turn kodi (the latest version, but also with old I have the same situation) with this systemd script :

[Unit]
 Description=Job that runs Kodi
 After=default.target graphical.target getty.target sound.target
[Service]
 User=kodi
 Restart=always
 RestartSec=1s
AE_SINK=ALSA
ExecStart = /usr/bin/xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/kodi-standalone -- :0 -nolisten tcp vt7
[Install]
 WantedBy=default.target

Sorry for my English, I am using a translator 

Here the log u need :

dpkg -l |grep mesa
DISPLAY=:0 vainfo 
cat ~/.kodi/temp/kodi.log​​​​​​​
dmesg | pastebinit​​​​​​​
id | pastebinit​​​​​​​
amixer | pastebinit​​​
cat /var/log/Xorg.0.log

use intel driver instead of modesetting

[Rumpelstiltskin]

?? How?

[wsnipex]

sudo apt install xserver-xorg-video-intel

[Rumpelstiltskin]

fatez@BlackBox:~$ sudo apt install xserver-xorg-video-intel
Lettura elenco dei pacchetti... Fatto
Generazione albero delle dipendenze
Lettura informazioni sullo stato... Fatto
xserver-xorg-video-intel is already the newest version (2:2.99.917+git20170309-0ubuntu1).

[FernetMenta]

you have to froce the driver in xorg.conf


Section "Device"
Identifier "Intel Graphics"
Driver "intel"
EndSection

[Rumpelstiltskin]

Thanks but i don't have xorg.conf :

fatez@BlackBox:~$ sudo locate xorg.conf
/usr/share/X11/xorg.conf.d
/usr/share/X11/xorg.conf.d/10-amdgpu.conf

I see what's happening. If you turn off passthrough audio, video gets smooth right?

They are better, what’s happening?

 First, running kodi-x11 without a window manager is not a supported environment. It may work but I have seen a lot of trouble with it.
This issue can be related to running without a wm. Before going any further, I suggest to fix the basics.

[Rumpelstiltskin]

I run it :

[Unit]
 Description=Job that runs Kodi
 After=default.target graphical.target getty.target sound.target
[Service]
 User=kodi
 Restart=always
 RestartSec=1s
AE_SINK=ALSA
ExecStart = /usr/bin/xinit /usr/bin/dbus-launch --exit-with-session /usr/bin/kodi-standalone -- :0 -nolisten tcp vt7
[Install]
 WantedBy=default.target

So i dont have a wm
