Hard to pin down whats causing this but every now and then sound is lost and a buzzing sound is played, the kodi.log starts showing errors around ActiveAE. Stopping and starting kodi does not resolve the situation only a full reboot. Can go days without a re occurrence, can happen watching TV , or recorded content. latest occurrence occurred while watching you-tube clips.

ERROR: ActiveAE::InitSink - failed to init
ERROR: ActiveAE::FlushEngine - failed to flush

Upgrade your kernel, please.

Upgrade your kernel, please.

Thanks upgraded to 4.4.0-93 is what you were thinking (staying on LTS) or would you rather i grabbed a 4.11 or 4.12 kernel

also had it happen again today watching youtube and stumbled across this as a possible solution.

I have removed my asound.conf for now and will see how it goes with a newer kernel.

Thanks

thanks. I remember that they asound.conf was for getting sound working if i ran MAME in the same way as i run kodi. have commented it out for now.

Broadcom wifi driver not supported ,- typical with newer kernels (I don't use it so not an issue)
also looks like firmware for Kerbylake, skylake and broxton cpu's is missing, Im on haswell so shouldn't be an issue.

Fixed the above issues. patched wifi source and firmware located for the newer Intel chips. will see how it goes. (reminds me of why i like to stay on the LTS release if at all possible )

Instead of upgrading to the 4.12 mainline kernel, you simply could have upgraded to the Ubuntu LTS HWE kernel and graphics stack.

The HWE stack provides the new Ubuntu kernels and graphics stacks for the current LTS release.

Meaning 16.04.2 has the kernel and graphics stack from 16.10 (kernel 4.8), then 16.04.3 has the kernel and graphics stack from 17.04 (kernel 4.10), then 16.04.4 has the kernel and graphics stack from 17.10 (kernel 4.13) and so on...

Doing so is as simple as:

Code:

sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04

as outlined on:

Thanks ill remember that for next time, all the issues were able to be fixed with minimal effort, ill stick with the mainline kernel till 18.04 lts next year.

I don't think the kernel was at fault this time and it was more to do with the long forgotten asound.conf i had lying around. The asound.conf was set to re sample to 48000hz. I have now removed it and played lots of 44100 content and had no further problems.

Its possibly a alsa bug, when you play content with 44100hz audio with the below asound.conf every now and then it falls apart.

asound.conf

I remember compiling kernels around the 3.18 era to fix haswell hdmi bugs. eventually fixed in kernel 3.19 IIRC due to being an early adopter of the Haswell gen CPU's not all was well for quite some time. But thanks to all the work from Fritsch and others we are now in great shape.

Hi, i got a Deskmini with Kaby Lake and Ubuntu 17.04 Server with Kernel 4.12.14

I followed all steps from first post. But i get one big issue: my usb-keyboard, usb-mouse and 2.4ghz remote doesn't work.

Kodi starts up after boot. Kodi log doesn't show any keyboard-issue. Looking with dmesg, my rf-usb-dongle is recognized fine and testing rf-inputs with lirc/irw the buttons works fine.

Kodi doesn't seem to be freezed, the clock on upper right side is going straight forward...
Looking if there would be any right-issues with user kodi, i wanted to start kodi with root-user. But if i change user in kodi.service to root, i don't get kodi-screen at all, there is only black screen but WITH mouse pointer.

Any help is appreciated. Thanks

EDIT:

vainfo is not installable cause conflict with libva but i think its not important, isn't it?

apt install vainfo
vainfo depends from libva1 < 1.7.3.1, but 1.8.3-1 is installed

When using hardware graphic acceleration video skipping performance is much worse than with just CPU. Is this a known "feature" or something wrong in my system? CPU is i7 Haswell with internal Intel graphics, H87 chipset.

I mean a situation where you are using fixed 20 second skip and press the button continuously or keep the button pressed i.e. skips are continuously repeating. With VAAPI skipping slowness/delays are still accetable but with VDPAU and Nvidia video card skipping was quite bad, it had long delays/pauses. In Kodi.log there appears a lot of lines like this, with Nvidia card there was much more stuff like loading sharpess etc. Looks like after each skip step these same lines appear, those lines do not appear when using CPU :

Hi fritsch,

I'm currently running ubuntu 16.04 server with your 4.9.6 custom kernel for 16:235 pass-through mode. I noticed recently in your kernel directory 4.13.0-rc7 but pass-through mode does not seem to be implemented there. Why?

Is there any reason for me to upgrade beyond 4.9.6? My system is HSW i5 and stuff has been running smoothly. I don't have a 4k tv.

Thanks as always for your great work!

No need. Just make sure to use vaapi / libva >= 1.7.3 as there was a quality related fix. If you have VC-1 files with adaptive tone, you should backport three additional commits. LE has all of them.
